What people call the scientific method, he explains, is really the Islamic method: “All the wealth of knowledge in the world has actually emanated from Muslim civilization. The Prophet Muhammad said to seek knowledge from the cradle to the grave. The very first verse came down: ‘Read.’ You are required to try to know something about your creator through meditation, through analysis, experimentation, and observation.”

Author, newspaper columnist, and television personality El-­Naggar is also a geologist whom many Egyptians, including a number of his fellow scientists, regard as a leading figure in their community. An expert in the somewhat exotic topic of biostratification—the layering of Earth’s crust caused by living organisms—El-Naggar is a member of the Geological Society of London and publishes papers that circulate internationally. But he is also an Islamic fundamentalist, a scientist who views the universe through the lens of the Koran.

Religion is a powerful force throughout the Arab world—but perhaps nowhere more so than here. The common explanation is that the Egyptian people, rich and poor alike, turned to God after everything else failed: the mess of the government’s socialist experiment in the 1960s; the downfall of Gamal Abdel Nasser’s Arab nationalism; the military debacle of the 1967 war with Israel; poverty; inept government—the list goes on.

I witness firsthand the overlapping strands of history as I navigate the chaos of Cairo, a city crammed with 20 million people, a quarter of Egypt’s population. In residential neighborhoods, beautiful old buildings crumble, and the people who live in them pile debris onto rooftops because there is no public service to take it away. Downtown, luxury hotels intermingle with casinos, minarets, and even a Pizza Hut. The American University in Cairo is a short distance from Tahrir Square, a wide traffic circle where bruised old vehicles brush pedestrians who make the perilous crossing. At all hours men smoke water pipes in city cafés; any woman in one of these qawas would almost certainly be a foreigner. Most Egyptian women wear a veil, and at the five designated times a day when the muezzins call, commanding the Muslims to pray, the men come, filling the city’s mosques.

The Islamic world looms large in the history of science, and there were long periods when Cairo—in Arabic, El Qahira, meaning “the victorious”—was a leading star in the Arabic universe of learning. Islam is in many ways more tolerant of scientific study than is Christian fundamentalism. It does not, for example, argue that the world is only 6,000 years old. Cloning research that does not involve people is becoming more widely accepted. In recent times, though, knowledge in Egypt has waned. And who is accountable for the decline?

El-Naggar has no doubts. “We are not behind because of Islam,” he says. “We are behind because of what the Americans and the British have done to us.”

The evil West is a common refrain with El-Naggar, who, paradoxically, often appears in a suit and tie, although he is wearing a pale green galabiyya when we meet. He says that he grieves for Western colleagues who spend all their time studying their areas of specialization but neglect their souls; it sets his teeth on edge how the West has “legalized” homosexuality. “You are bringing man far below the level of animals,” he laments. “As a scientist, I see the danger coming from the West, not the East.”

He hands me three short volumes he has written about the relationship of science and Islam. These include The Geological Concept of Mountains in the Holy Koran, and Treasures in the Sunnah, A Scientific Approach, parts one and two, along with a translation of the Koran, whose title page he has signed, although his name does not appear as a translator.

In Treasures in the Sunnah, El-Naggar interprets holy verses: the hadiths, sayings of the Prophet, and the sunnah, or customs. There are scientific signs in more than one thousand verses of the Koran, according to El-Naggar, and in many sayings of the Prophet, although these signs often do not speak in a direct scientific way. Instead, the verses give man’s mind the room to work until it arrives at certain conclusions. A common device of Islamic science is to cite examples of how the Koran anticipated modern science, intuiting hard facts without modern equipment or technology. In Treasures of the Sunnah, El-Naggar quotes scripture: “and each of them (i.e., the moon and the sun) floats along in (its own) orbit.” “The Messenger of Allah,” El-Naggar writes, “talked about all these cosmic facts in such accurate scientific style at a period of time when people thought that Earth was flat and stationary. This is definitely one of the signs, which testifies to the truthfulness of the message of Muhammad.”

Elsewhere, he notes the Prophet’s references to “the seven earths”; El-Naggar claims that geologists say that Earth’s crust consists of seven zones. In another passage, the Prophet said that there were 360 joints in the body, and other Islamic researchers claim that medical science backs up the figure. Such knowledge, the thinking goes, could only have been given by God.

Critics are quick to point out that Islamic scientists tend to use each other as sources, creating an illusion that the work has been validated by research. The existence of 360 joints, in fact, is not accepted in medical communities; rather, the number varies from person to person, with an average of 307. These days most geologists divide Earth’s crust into 15 major zones, or tectonic plates.

El-Naggar even sees moral meaning in the earthquake that triggered the 2005 tsunami and washed away nearly a quarter of a million lives. Plate tectonics and global warming be damned: God had expressed his wrath over the sins of the West. Why, then, had God punished Southeast Asia rather than Los Angeles or the coast of Florida? His answer: Because the lands that were hit had tolerated the immoral behavior of tourists
