Muhammad bin Yahya bin Hiban محمد بن يحيى بن حبان · The Book of Purification

"I climbed on the roof of our house and saw the Messenger of Allah (ﷺ) on two bricks, facing toward Bait Al-Maqdis (jerusalem), relieving himself."

"I noticed the Prophet (ﷺ) was not there one night, so I started looking for him with my hand. My hand touched his feet and they were held upright, and he was prostrating and saying: 'I seek refuge in Your pleasure from Your anger, in Your forgiveness from Your punishment, and I seek refuge in You from You. I cannot praise You enough, You are as You have praised yourself.'"

"If the Prophet (ﷺ)" - (one of the narrators) 'Amr said: "If the Messenger of Allah (ﷺ)" - "wanted to eat or sleep while he was Junub, he would perform Wudu'." In his narration, 'Amr (one of the narrators) added: "Wudu' was for prayer."

"We did Tayammum with the Messenger of Allah (ﷺ) using dust, and we wiped our faces and our arms up to the shoulders."
