According to all Muslims, the central and defining experience in Muhammad’s life occurred in the year 610 C.E. in his initial encounter with an angel, usually identified as Gabriel, an event that marked the beginning of his revelations.33 For some time before this dramatic event, Muhammad had been in the habit of withdrawing to a cave outside Mecca for prayer and meditation. On this occasion, however, a towering and overpowering presence of the angel appeared to him, filling the entire horizon, squeezing the very breath from his body, and commanding him to “recite” or to “read.” After repeated protests that “I am not a reciter/reader,” Muhammad found himself speaking what became the first revelation of the Quran.

When the vision passed, Muhammad fled in terror to his wife Khadija, fearing that he might be mad or possessed of some demonic spirit. Seeking to comfort him, Khadija took her husband to her learned cousin Waraqa, a Christian, who assured Muhammad that “he is the prophet of his people” and the recipient of revelation from the same God who had earlier granted similar messages to Abraham, Moses, and Jesus, among others. Further revelations followed over the next twenty-two years until Muhammad’s death in 632, after which they were compiled into the Quran.
