Ayoub al-Sakhtiyani أيوب السختياني · The Book of Purification and its Sunnah

"The Messenger of Allah said: 'When a person performs ablution and washes his hands, his sins exit through his hands. When he washes his face, his sins exit through his face. When he washes his forearms and wipes his head, his sins exit though his forearms and head. When he washes his feet, his sins exit through his feet.'"

"The Messenger of Allah said: 'For cleaning yourself you need three stones, no one of them being dung.'"

"The Messenger of Allah performed ablution and wiped his head twice."

The Messenger of Allah slept until he was breathing deeply, then he got up and prayed.

"The Prophet came out and met me when I was sexually impure, so I kept away from him. Then I had a bath and came to him. He said: 'What is the matter with you?' I said: 'I was sexually impure.' The Messenger of Allah said: 'The Muslim does not become impure.'"
