It is narrated from Sayyiduna Abdullah ibn Abbas (may Allah be pleased with him), he says: I came to the service of the Messenger of Allah (peace and blessings be upon him) in the last part of the night. I began to pray behind him, but the Messenger of Allah (peace and blessings be upon him) took my hand, pulled me forward, and made me stand next to him at his side. When the Messenger of Allah (peace and blessings be upon him) turned towards the prayer, I slipped back a little. When the Messenger of Allah (peace and blessings be upon him) completed the prayer, he said to me: What happened to you? I made you stand next to me, but you slipped back? I replied: O Messenger of Allah! You are the Messenger of Allah, Allah has granted you a great rank and status. Is it appropriate for someone like me to stand next to you and pray? My words pleased you very much, and you prayed to Allah for me that Allah increase me in knowledge and understanding. After that, I saw the Messenger of Allah (peace and blessings be upon him) sleep so deeply that he began to snore. Then Sayyiduna Bilal (may Allah be pleased with him) came and called out to the Messenger of Allah (peace and blessings be upon him): O Messenger of Allah! The time for prayer has come. So the Messenger of Allah (peace and blessings be upon him) got up and performed the prayer, and did not perform ablution again (because during sleep, the heart of the Messenger of Allah (peace and blessings be upon him) remains awake).
