Qatada قتادة · The Book on Purification

"Encourage your Husbands to clean themselves with water, for I am too shy of them, and Allah's Messenger would do that."

the same from the Prophet.

"Some people from Urainah arrived in Al-Madinah, and they were uncomfortable (and ill from the climate). So Allah's Messenger sent them some camels from charity. He told them: "Drink from their milk and urine." So they killed the camel driver that Allah's Messenger sent, and they violently drove off the camels, and apostatized from Islam. So the Prophet came to them, he cut off their hands and feet on opposite side, and branded their eyes, and threw them in Al-Harrah."…

he saw the Prophet sleeping, while in the prostration position, until he snored or snorted. Then he stoodup to pray. So I said: "O Messenger of Allah! You were sleeping?" He said: "Wudu is not required except for sleeping while reclining. For when one reclines, joints relax."

"The companions of Allah's Messenger would sleep, then stand to pray, They would not perform Wudu."

"Allah's Messenger would go around to his women with one Ghusl."

the Prophet ordered him to perform Tayammum by rubbing his face and two palms.
