Chapter: Sleeping of a men in the mosque

`Abdullah bin `Umar said: I used to sleep in the mosque of the Prophet (ﷺ) while I was young and unmarried.

Allah's Messenger (ﷺ) went to Fatima's house but did not find `Ali there. So he asked, "Where is your cousin?" She replied, "There was something between us and he got angry with me and went out. He did not sleep (midday nap) in the house." Allah's Messenger (ﷺ) asked a person to look for him. That person came and said, "O Allah's Messenger (ﷺ)! He (Ali) is sleeping in the mosque." Allah's Messenger (ﷺ) went there and `Ali was lying. His upper body cover had fallen down to one side of his body and he was covered with dust. Allah's Messenger (ﷺ) started cleaning the dust from him saying: "Get up! O Aba Turab. Get up! O Aba Turab (literally means: O father of dust).

I saw seventy of As-Suffa men and none of them had a Rida' (a garment covering the upper part of the body). They had either Izars (only) or sheets which they tied round their necks. Some of these sheets reached the middle of their legs and some reached their heels and they used to gather them with their hands lest their private parts should become naked.
