Ibn 'Abbas said, "The Prophet slept till he snored and then prayed (or probably lay till his breath sounds were heard and then got up and prayed)." Ibn 'Abbas added: "I stayed overnight in the house of my aunt, Maimuna, the Prophet slept for a part of the night, (See Fateh-al-Bari page 249, Vol. 1), and late in the night, he got up and performed ablution from a hanging water skin, a light (perfect) ablution and stood up for the prayer. I, too, performed a similar ablution, then I went and stood on his left. He drew me to his right and prayed as much as Allah wished, and again lay and slept till his breath sounds were heard. Later on the Mua'dhdhin (call-maker for the prayer) came to him and informed him that it was time for Prayer. The Prophet went with him for the prayer without performing a new ablution." (Sufyan said to 'Amr that some people said, "The eyes of Allah's Apostle sleep but his heart does not sleep."
