“The Koran is the holy book about whose compositional process we know most. There were at least two mediations between the whole and the book: Mohammed listened to the word of Allah and dictated, in his turn, to his scribes. Once—the biographers of the Prophet tell us—while dictating to the scribe Abdullah, Mohammed left a sentence half finished. The scribe, instinctively, suggested the conclusion. Absently, the Prophet accepted as the divine word what Abdullah had said. This scandalized the scribe, who abandoned the Prophet and lost his faith.
He was wrong. The organization of the sentence, finally, was a responsibility that lay with him; he was the one who had to deal with the internal coherence of the written language, with grammar and syntax, to channel into it the fluidity of a thought that expands outside all language before it becomes word, and of a word particularly fluid like that of a prophet. The scribe’s collaboration was necessary to Allah, once he had decided to express himself in a written text. Mohammed knew this and allowed the scribe the privilege of concluding sentences; but Abdullah was unaware of the powers vested in him. He lost his faith in Allah because he lacked faith in writing, and in himself as an agent of writing.”
