The Quran is the Book of Allah (God) that was revealed in Arabic to the Prophet Muhammad (peace be upon him) over a period of twenty-three years.
He dictated it to his followers as he received it from the Angel Jibril (Gabriel), and they wrote it down on whatever materials were available. The Prophet and many of his followers memorized it as it was revealed.
The Quran consists of 114 surahs (chapters) of various lengths, from 3 to 286 verses. The verses were revealed a few at a time and not in their present order but were placed in their position by the Prophet in accordance to instructions from the Angel Jibril.
Shortly after the death of the Prophet Muhammad, the first caliph, Abu Bakr As-Siddiq, ordered the scribe Zayd ibn Thabit to collect the manuscripts and make one copy of the Quran. He did so with the assistance of the hundreds of Companions of the Prophet who had memorized the Quran, thus assuring that nothing was added or omitted, and that the order of the verses was according to the Prophet’s instructions.
