How revelation began and what was first revealed
Narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him): Allah sent down revelation to His Messenger (peace and blessings of Allah be upon him) frequently before his death, until near his death, revelation came in abundance. Then after that, the Messenger of Allah (peace and blessings of Allah be upon him) passed away.
