Birth of a religion

An interview with Tom Holland, author of In the Shadow of the Sword.

How much do we know about the birth of Islam? Much less than we think, argues the popular historian Tom Holland in his new book, In the Shadow of the Sword.

In Holland’s opinion, the Quran was written long after the death of Muhammad, Mecca is not necessarily the birthplace of the Prophet and modern Muslims’ reverence for their holy writings stops them from confronting the texts’ dubious historical origins.

Bryan Appleyard has described the conclusion of In the Shadow of the Sword as “seismic”; he wrote in the Sunday Times that “Holland’s book leaves almost no aspect of the traditional story of Islam intact”. Another reviewer likened its treatment of the Quran to Dan Brown’s Christianity-as-conspiracy in The Da Vinci Code, “though with a little more class”.

The religion that emerged as Islam by the 8th century was, Holland would argue, just one manifestation of the furthest-reaching moral and ethical metamorphosis in history. Other expressions of the phenomenon were what we now call Judaism and Christianity – faiths that he suggests had taken on something like the form they wear today by the time of Muhammad, but similarly were once swirls of beliefs and doctrines.

Holland’s tale of how Islam came to define itself and its past is only one part of a much broader panorama: one that is ultimately about how Jews, Christians and Muslims all came by their understanding of religion. Does he present a bold new account that undermines Islam’s grip on its own past, or, as I argue, spin out a rich but speculative tale of the possible birth of three religions as novel tools to grapple with an era of geopolitical conflict and rivalry?

Nabeelah Jaffer

Nabeelah Jaffer Your chapters on the ambi­guity of early Christianity and Judaism have slipped under the radar amid the general buzz that you “rubbish” Islam and the expectant wait for some sort of backlash. How doyou feel about the assumption that Muslims are more likely to respond to challenging ideas with violent anger than followers of other religions? And do you think there will be a few far-right attempts to appropriate your ideas?

Tom Holland I think it is one measure of theeffect of the [Salman] Rushdie affair in this country that it is now widely taken for granted that writing anything about Islam will make angry men with beards – and probably hooks as well! – come to kill you. Whenever I have told people what the book was about, the word “fatwa” has invariably surfaced.

That being so, it was probably inevitable that the most eye-catching chapters in the book would be the ones about Islam. But why should any Muslim be offended by what I have to say? Mine is a non-believer’s attempt to explain a puzzle that Muslims, if they have faith, would deny was a puzzle at all. As an adult, I struggle to square my absolute conviction that Abraham and Moses never existed with the occasional flaring of a residual Christian faith. I hope that the resulting tension has been good for the book. Yes, it is sceptical; but no, it is never contemptuous of the longing of people to know God.

NJ I agree. I think both upset Muslims and pleased “Islamophobes” perceive in revisionism a threat to the religious narrative where none exists. The questions that you set out to answer only appear when you take a divine presence out of the equation.

You wrestle, for example, with the “bewilderingly eclectic array of sources” in the Quran, Abrahamic and otherwise. A Muslim would take this as proof of divine input and a revelation which encompasses Judaism and Christianity as part of a prophetic tradition. As a non-Muslim, you rule out this answer and search for an alternative scenario. Presenting a potential secular alternative to the “God” story doesn’t negate the narrative upheld by believers. So, turning to your secular alternative, how does it differ from traditional accounts?

TH All three religions, it seems to me, emerged out of the same melting pot – and yet all three have constructed backstories that aim to occlude the fact. In the first three centuries after Christ, Jews and Christians may have had a consciousness of themselves as peoples with distinct identities, but they remained unclear where precisely the border between them lay.

There were Jews who believed that Jesus had been the Messiah and there were Christians who followed the Jewish law – and it took an unacknowledged alliance between bishops and rabbis, in the centuries after the emperor Constantine, to ensure that what had previously been an open frontier became a no-man’s land. Similarly, a lot of Muslim historiography seems to me to have been composed with the aim of spiking the possibility that either the Quran or the sunna [laws] might conceivably have owed anything to infidel precedent.

NJ Of course, one of the first things you learn as a historian is to interrogate early chronicles for motive using context, whether geopolitical, religious or otherwise. But it is equally dangerous to lean towards the hypersceptic idea that texts cannot be relied upon except to tell us about their writers, meaning the document-free gaps in the past must always consist of near-impregnable darkness.

You don’t go quite that far in your book, but you do apply something of this very sceptical view to early Islamic sources which first appeared in the 200 years after the Prophet’s death as written accounts of oral testimony. You suggest, for example, that hadiths [sayings of Muhammad] targeting the rich were concocted to unsettle the rotten imperial elite. Your argument that “the dry rot of fabrication . . . was endemic throughout the sunna” is much more radical than the traditionalist, more common academic approach, which recognises the importance of testing for fabrication, but values the hadith as a body of secondary sources. I’d disagree that uncovering fabricated elements in these early sources undermines everything that they portray as authentic.

TH I think there’s a particular problem with the sources for early Islam. Some of the sayings attributed to Muhammad must surely be authentic – but even if we could identify them, their value as a source for his life would still not be greatly enhanced as a result.

Context, for the historian, is all – and no Muslim scholar or lawyer who cited the Prophet ever had the slightest interest in establishing what the original context of his sayings might actually have been. To quote him was to take for granted that the advice he had to give was timeless and universal. That Muslims in the heyday of the Caliphate were living under circumstances unimaginable to Muhammad never crossed their minds.

The real problem for the historian is that we lack what, for instance, [the 1st-century Roman-Jewish historian] Josephus gives us for the background to the life of Christ – a control. The consequence is that we can only hope to arrive at a sense of what might have happened in the early years of the Arab conquests by looking at the much later Muslim source material in the light of the late-antique world.

NJ In which case, no explanation of the origins of Islam is ever going to strike the mould for an authentic secular narrative. You rightly point out in your introduction the provisional nature of your own retelling of early Islam: “on a whole range of issues . . . there can only ever be speculation”. While you use Christian and Jewish traces in the Quran to suggest their influence on Muhammad, direct evidence remains elusive.

There’s a wonderful analogy in the book about it being similar to noticing that the eastern and western coasts of the Atlantic Ocean match like a jigsaw puzzle. There seems to be a link, but without clues as to how the two came together, it’s impossible to know for certain how to explain the gap. Historians are just replacing one take on an uncertain past with another.

TH The hypothesis I give in the book as to how and why Islam might have emerged is only that – a hypothesis. Patricia Crone, one of the most brilliant and innovative historians of early Islam, once memorably described the Muslim historical tradition as “a monument to the destruction rather than the preservation of the past”. That being so, it is hardly surprising that there should be such a breathtaking range of opinion, ranging from devout Muslims, who accept the tradition in its entirety, to radical sceptics who doubt that Muhammad so much as existed.

My own take is that the evolution of Islam can only really be made sense of in the light of the civilisations and religions of late antiquity. Partly, that is because it genuinely seems to me the best way to try to understand what might have happened in the 7th century; but I am sure it also reflects a subliminal desire on my part, in love with antiquity as I am, to feel that Islam, like Christianity, was bred of the ancient world.

NJ This debate has, until now, been limited to specialists, for the good reason that it requires a vast amount of study and a good knowledge of Arabic, at least, in order to draw authoritative conclusions from the available sources. Revisionists are few, and those such as Patricia Crone and Michael Cook who argue that Islam was born after the burgeoning of the Caliphate and the Arab conquests do so with the authority of their close understanding of the period, albeit little concrete evidence.

While you obviously draw on the work of such historians and are enthusiastic about the period, is it fair to present a narrative not grounded in direct engagement with the available sources?

TH In writing this book, I am standing on the shoulders of giants – or, to mix metaphors, rushing in where angels fear to tread. My justification is that if a generalist is not prepared to attempt it, then no one will. Perhaps, somewhere, there is a scholar with Latin, Hebrew, Syriac, Arabic and Coptic, doctorates in Talmudic studies, patristics, Christian theology and Quranic studies and an ability to write accessibly for the general public – but if so, he or she is yet to write the book on the subject that I strongly felt merited being written.

Even the greatest historian of the decline and fall of the Roman empire, Edward Gibbon, had to profess his “ignorance of the Oriental tongues, and . . . gratitude to the learned interpreters”. Where I had the advantage, perhaps, was in having a brilliant research assistant, a native Arabic speaker with a specialisation in Syriac, and the incredible generosity of a wide range of scholars.

NJ Locating religious construction in the centuries that followed the death of Muhammad involves saying some particularly challenging things about the Quran and the Prophet himself. For example, you accept that the Quran seems to date from around Muhammad’s time, and certainly recent carbon-dating research suggests an early-7th-century date for indicative Quranic fragments.

When the German Quranic scholar Gerd Puin was allowed to examine the ancient manuscripts recently discovered in Sana’a, Yemen, he found possible evidence of minor changes to verse order and spelling, but uncovered no hint of deliberate fabrication. In the light of all this, proposing that figures such as the 7th-century caliph Abd al-Malik, whom you suggest put the Quran through an “editing process”, and the historian Ibn Hisham constructed a retrospective religion centred on a man named Muhammad, whom they situated in Mecca, seems a little extreme. There are direct mentions of Muhammad in the Quran itself, among dozens of other allusions to his life.

TH The problem for any non-Muslim trying to explain the origins of Islam is what to make of the Quran. It seems to me clearly to derive, in the form we have it, from the lifetime of Muhammad – which makes it, a few other brief and enigmatic documents aside, our only primary source for his career.

The problem is, I cannot possibly accept what Muslims take for granted: that it originates from God. And yet Mecca, so the biographies of the Prophet teach us, was an inveterately pagan city devoid of any large-scale Jewish or Christian presence, situated in the midst of a vast, untenanted desert. How else, then, are we to account for the sudden appearance there of a fully fledged monotheism, complete with references to Abraham, Moses and Jesus, if not as a miracle? You can only answer that question by asking yourself whether Muslims, at some point in the evolution of Islam, might not have situated the origins of the Quran deep in a desert for the same reason that Christians cast the mother of Christ as a virgin. In both cases, what is presumed to be an intrusion of the divine into the dimension of the mortal is being certified as an authentic, bona fide act of God.

NJ I don’t argue that religious practices shouldn’t be understood as firmly within their political and cultural contexts as possible. But religions are necessarily a human phenomenon in their practice, however divine we believe their inspiration and aspiration to be. “Monotheistic revolution” is a misnomer: the evolution of faith didn’t end with the melting pot of Byzantine.

TH I think in the early history of what emerges as rabbinical Judaism, of Christianity and of Islam, you see a near-identical process: the gradual fashioning, out of a great swirl of often inchoate rituals, convictions and scriptures, of a distinct religion that is coherent, in terms of both doctrine and institutions. Watchtowers and barriers go up, the aim being to keep the faithful inside set limits and to keep non-believers out. Histories are then written which make it seem as though the religion has always existed in the form that it now possesses, right from the very beginning – that Moses was a rabbi, that Jesus would have signed up to the Nicaean Creed, that Muhammad was truly the fountainhead of the sunna.

The concrete, initially so soft and malleable, by now has set. This does not mean, of course, that the various religions do not continue to evolve – but they do so within parameters that by now are irrevocably rigid, and exclude contributions from peoples of other faiths. It is in that sense, I would argue, that Jews, Christians and Muslims all today worship different gods.

Chill out

Stress is not as destructive as is often assumed: a little bit of it may even be good for us.

It creeps up on you as soon as the alarm clock rings. Fingers reflexively unlock your phone. Emails bound in with a jolly ping: things you should have done last week; pointless meeting requests; bills to pay.

Over a hurried breakfast you scan the headlines: wall-to-wall misery. On the train you turn to social media for relief. ­Gillian is funnier than you. Alex got promoted again. Laura’s sunning herself in Thailand. You’re here, packed in, surrounded but alone, rattling your way towards another overstretched day.

Stress: we know what it feels like, we can smell it on others, we complain about it most days. And we’re living through an epidemic of it. The government’s Health and Safety Executive estimates that stress cost the economy nearly ten million working days last year. Some 43 per cent of all sick days were attributed to stress. In the US, a large survey conducted by the National Public Radio network in 2014 showed that nearly one in two people reported a major stress event at some point in the previous 12 months. The year before that, American doctors wrote 76 million unique prescriptions for the anti-anxiety drugs Xanax and Ativan. With the media running stories about stress-induced heart disease, strokes, obesity, depression, ulcers and cancer, it’s hard not to conclude that stress kills.

But consider this: just a century ago, nobody got stressed. They suffered with their nerves, got a touch of the vapours; they worried; but they were never stressed. In fact, our current view of stress – what it is, what it feels like, and when it is harmful – evolved surprisingly recently. And research shows that the way we think about stress has a profound influence on how it affects us.

Prolonged, uncontrollable stress – particularly if suffered in childhood – can be profoundly corrosive and debilitating. But what of the familiar stresses of day-to-day life? Are they actually damaging you? Might the belief that stress is harmful be self-fulfilling? And what would a stress-free life look like? Instead of turning in on ourselves and doing battle with our personal stress demons, might we be able to put their diabolic energy to good use?

If we pause for a moment from our daily hustle we would see that many of us are incurably hooked on stress. We thrive on it, getting a kick out of surviving the high-stakes presentation, meeting the deadline and overcoming our fears and prejudices. Watching a thriller, we are on the edge of our seat, pulses racing. Sports, on the field or on television, can propel us into “fight or flight” mode. Humanity’s fascination with gambling hinges on stress.

If the most skilled physiologists in the world could peer beneath the skin of a thrill-seeker on a roller coaster and an out-of-his-depth job interview candidate, they would struggle to tell them apart. Deep in the brain, they would see a structure called the hypothalamus fired up. With each lurch of the ride or disarming question asked, the hypothalamus signals to the adrenal glands, which sit atop each kidney. The adrenals then squirt a shot of adrenalin into the bloodstream. In the background, the hypothalamus prods the pituitary gland, which passes a different message on to the adrenal gland. This increases production of cortisol, the textbook “stress hormone”. Flipping these biological switches triggers the familiar bodily symptoms of stress: a pounding heart, raised blood pressure, dilated pupils, arrested digestion and a damped-down immune system. In both cases, the biological stress response would look very similar.

Even if we could eliminate stress entirely, or smother it with pharmaceuticals, we wouldn’t want to. To muzzle the stress response is to silence the good as well as the bad. At best, stress can motivate us to achieve more and fix the sources of our stress. Boredom is stressful in its own way: observe a caged lion, or an understimulated teenager. In fact, as the animal psychologist Françoise Wemelsfelder told New Scientist recently, boredom may exist to spur us back into activity. This half-forgotten idea, that some degree of stress can inspire and elevate, is common sense. It also has deep roots in the earliest scientific study of stress and stress responses.


At the beginning of the 20th century, two American psychologists, Robert Yerkes and John Dodson, wanted to know how stressing out lab mice affected their learning. They set the rodents navigational challenges and punished wrong turns by administering small electric shocks to the feet. In their terminology, larger electric currents caused greater “arousal”.

They spotted some consistent trends. When they gave mice an easy task (choosing between a black or a white tunnel) the relationship between the strength of the shock and the speed of learning was simple. The greater the stressor, the quicker the mice learned to pick the right tunnel.

When the challenge was subtler (differentiating between grey tunnels), the response was less straightforward. Weak shocks provided little impetus to learn, but as the zaps got stronger, the mice gradually upped their game. They focused on the task and remembered the consequences of wrong choices. Yet, at a certain point, the high stress levels that helped with the easy task became counterproductive. Overwhelmed, the mice skittered around at random, trying in vain to escape.

On a graph, the relationship between stress and performance on onerous tasks traces an inverted U shape. Some degree of stress helps, but there is a clear tipping point, beyond which stress becomes paralysing. The findings became known as the Yerkes-Dodson law.

This was all very well for mice, but could it be applied to human beings? According to the Canadian-Austrian endocrinologist Hans Selye, the “father of stress”, it could. Selye was the first person to describe the key glands, hormones and nerves of the biological stress response during the 1930s and 1940s, and also one of the first to apply the word “stress” to human biology.

For Selye, “stress” described an all-purpose response the body had to any demand placed upon it. When stress is on the upswing of Yerkes and Dodson’s inverted-U performance curve, Selye calls it “eustress”. This is where good teachers and managers should push their charges: to the sweet spot that separates predictable tedium from chaotic overload. Where stress gets more persistent, unmanageable and damaging, Selye calls it “distress”. Eustress and distress have identical biological bases; they are simply found at different points on the same curve.

Despite this knowledge, stress has a terrible public image today, often synonymous with distress. While some wear their stress as a badge of honour (“I’m important enough to be stressed”), deep down even the most gung-ho City workers probably stress about their stress. And in painting stress as a beast, we grant it more destructive power.

When did we come to view stress as the universal enemy? Mark Petticrew, Professor of Public Health Evaluation at the London School of Hygiene and Tropical Medicine, has sifted through a huge archive of historical tobacco industry documents. In a 2011 paper, he revealed that a large proportion of stress research during the second half of the 20th century was funded, steered and manipulated by this most unexpected of benefactors. Indeed, from the late 1950s, Hans Selye received hundreds of thousands of tobacco-stained dollars. He also allowed industry lawyers to vet his research and appeared in several pro-tobacco propaganda films.

“They put a massive, massive amount of money into it,” Petticrew told me.

Why were tobacco manufacturers so interested in stress? First, cigarettes were marketed as a stress reliever. “To anxiety . . . I bring relief,” reads a 1930s advertisement for Lucky Strike. So if research could help them pin poor mental and physical health to stress, this sort of message would carry more weight. (Incidentally, the still widespread belief that smoking reduces anxiety appears to be wrong.)

Later, as evidence grew that smoking caused cancer and heart disease, the tobacco industry wanted to prove that stress was an equally significant risk factor. They used the authority of Selye and several other leading researchers as a smokescreen. “Doubt is our product,” read a top industry executive’s 1969 memo. And so doubt they sowed, arguing repeatedly that stress was a major cause of disease. Those seeking to control tobacco were wrong, they claimed.

It worked: the industry convinced the general public of the evils of stress and diverted public health research for at least a decade. With tobacco regulation and compensation payouts postponed, the profits kept rolling in.

Should we doubt the veracity and neutrality of all the foundational research into stress as a disease? “I wouldn’t want to argue that stress doesn’t exist, or that it isn’t bad for your health and certainly your mental health,” Petticrew says. “But you can’t ignore this story.”

He goes on to describe concrete “findings” that industry-funded researchers got wrong. Prominent among these was a link between coronary disease and people displaying so-called Type A personality traits: competitiveness, ambition, anxiety. Such temperamentally “stressed” people were especially likely to suffer heart attacks and, not coincidentally, to smoke. Then the association faded away. “Aside from the scientific weaknesses, which are many, Type A is a cultural artefact to some extent constructed by the tobacco lobby,” Petticrew says. And yet, despite its fragile foundations, the Type A myth persists today.

The long shadow cast by decades of one-sided, propaganda-laced stress research has led many people to believe that stress is a direct cause of heart attacks. But the British Heart Foundation’s website states, “There is no evidence to suggest that stress causes coronary heart disease or heart attacks.” Nor does it cause stomach ulcers: usually it is a bacterium called Helicobacter pylori which does that.

The tobacco-funded researchers didn’t get it all wrong. Stress does have clear causal links to some diseases, particularly mental illnesses, including depression, anxiety disorders, schizophrenia and addictive behaviour. High stress levels appear to be a general risk factor for early death, among middle-aged men in particular. Moreover, we all know how unpleasant stress can be. From insomnia to binge eating and boozing, we respond to stress with all sorts of counterproductive and antisocial behaviours. And that is partly why the tone of messages we hear about stress matters so much. Human beings are inherently suggestible and particularly vulnerable to warning messages about our health, especially when those messages seem to be backed by science.


With mice in a cage, you can measure the tipping point – the precise current of the electric shock – where good stress becomes bad. But we don’t need the lurking menace of a lion in the long grass to activate our stress response. We can do it perfectly well for ourselves. All it takes is a negative thought, the memory of an insult, or a vague feeling of unease.

We can think our way into stress. And, as recent evidence shows, if we believe stress is going to hurt us, it is more likely to hurt us. This is one message emerging from the Whitehall II project, a long-term study of 10,000 UK government civil servants, set up in 1985 to study the social, economic and personal determinants of health and disease. A 2013 analysis of Whitehall II data concluded that people who believe stress adversely affects their health are more than twice as likely to suffer a heart attack, irrespective of their stress levels.

There is a flipside to this gloomy news. If our thoughts and beliefs can switch on a damaging stress response, can they also switch it off? Could the power of suggestion be a partial vaccination in the battle against the stress epidemic?

This is the contention of Alia Crum, a psychology professor at Stanford University and a flagbearer for the science of mindset manipulations. In 2007 she showed that if hotel chambermaids come to think of their work as exercise, they lose weight and their blood pressure falls, apparently without them working any harder. More recently, she described how UBS bankers who were shown videos about the life-enhancing effects of stress – how it can sharpen attention, boost cognition and force fresh perspectives – reported being more productive, focused and collaborative, and less afflicted by depression and anxiety.

The inescapable conclusion is this: the human mind is a powerful gatekeeper to the stress response. But we have to tread carefully here. UBS employees may have the freedom to choose a less stressful life, and find opportunity to reshape their stress mindsets. What about those whose stress is delivered early and compounded by a lifetime of disadvantage and adversity? Perhaps this is where the story of familiar, workaday stress and the grinding strain of social injustice come together. Stress gets under our skin only when we can’t see the end or spot the fix. So what, other than using Crum’s mindset interventions, can we do to restore the critical feeling of empowerment?

Emily Ansell, an assistant professor of psychiatry at Yale, says that reaching out a kindly hand to your fellow human beings can be surprisingly helpful. In a study published last year, Ansell and colleagues gave a group of 77 people a diary-like smartphone app. They asked the subjects to record all the stressful incidents they encountered, and any minor acts of kindness they performed, during a 14-day period. The data shows that gestures such as holding doors for strangers and helping elderly people across the road buffer the effects of stress and make you feel more optimistic.

Positive interactions deliver a reward at the neurological level. They restore a sense of control and show that meaningful relationships are possible. Moreover, helpers often get more psychological and health benefits than those on the receiving end of  that help.

How do we encourage prosocial behaviour throughout society, particularly at the margins? According to Paul Piff, a social psychologist at the University of California, Irvine, lower-class people in America often “have less and give more”. They are more generous, charitable, trusting and helpful than their upper-class counterparts. It’s possible that this tendency to reach out and muck in is a direct response to a life of chronic stress. In response to Piff’s theory, Michael Poulin, a professor of psychology at the University of Buffalo, suggests: “We should perhaps really focus on encouraging prosocial behaviour among the well-off, ­potentially leading to benefits both for them – in terms of stress – and for the disadvantaged, who would presumably benefit from their generosity.”
