Each revelation was written down by the Prophet's scribes according to the Prophet's instructions. The current order and organization into the 114 chapters (surahs) of the entire revelations were therefore given to us by the Prophet himself.

There are thousands of such Muslims who, known as Hafiz, usually one for each Mosque in Muslim countries. Copyright © Iqra Inc. All Rights Reserved .
