O Messenger of Allah, may anyone of us sleep while being ritually impure? He said: Yes, he may sleep if he makes ablution When anyone of you performs ablution, let him sniff water in his nose and then blow it out. Whoever cleans his private parts with stones, let him do so with an odd number of stones. Whoever wakes up from his sleep, let him wash his hands three times before putting them in the water vessel, for none of you knows where his hands were during his sleep Do not keep the fire burning in your homes when you go to bed When he went to bed every night, he would join his palms together and blow into them He said: Say: O Allah, Creator of the heavens and the earth, Knower of the hidden and the apparent, Lord of everything and its Possessor, I bear witness that there is no god but You. I seek refuge in You from the evil of my own self and from the evil of the devil and the evil of polytheism to which he calls. This fire is your enemy, so put it out before going to bed When the Messenger of Allah wanted to sleep, he would put his right hand under his cheek, and then say: O Allah, safeguard me from Your torment on the day You resurrect Your slaves
