Hameed bin Abi Hameed حميد بن أبي حميد الطويل · The Book of Purification

"The Messenger of Allah (ﷺ) stayed behind, and I stayed with him. When he had relieved himself he said: 'Do you have any water with you?' I brought some water to him, and he washed his hands and face, then he started trying to uncover his arms, but the sleeves of his Jubbah were too tight, so he threw it over his shoulders and washed his arms and wiped over his forehead and 'Imamah, and over his Khuff."

It was narrated from Anas that the Messenger of Allah (ﷺ) used to (go around) all his wives and perform Ghusl once.

"While the Messenger of Allah (ﷺ) was in the Masjid, he said: 'O 'Aishah, hand me the garment.' She said: 'I am not praying.' He said: 'It is not in your hand.' So she gave it to him."

"When any one of you prays, let him not spit in front of him or to his right, rather let him spit to his left or beneath his feet." Then the Prophet (ﷺ) spat like this on his garment and rubbed it.
