al-Mqdam bin Shryh bin Han'i المقدام بن شريح بن هانئ بن يزيد · The Book of Purification

"I said to 'Aishah: 'What did the Prophet (ﷺ) start with when he entered his house?' She said: 'The Siwak.'"

"Whoever tells you that the Messenger of Allah (ﷺ) urinated standing up, do not believe him, for he would not urinate except while squatting."

"While I was menstruating, I would nibble meat from a bone, and the Messenger of Allah (ﷺ) would put his mouth where mine had been. And while I was menstruating, I would drink from a vessel and he would put his mouth where mine had been."

"I heard 'Aishah say: 'The Messenger of Allah (ﷺ) would hand me the vessel and I would drink from it, while I was menstruating, then I would give it to him and he would look for the place where I had put my mouth and put that to his mouth.'"

"I would drink while I was menstruating, then I would hand it to the Prophet (ﷺ), and he would put his mouth where mine had been and drink. And I would nibble at the bone on which some bits of meat were left while I was menstruating, then I would give it to the Prophet (ﷺ) and he would put his mouth where my mouth had been."

"While I was lying down with the Messenger of Allah (ﷺ) under a blanket, my period came, so I slipped away and put on the clothes I used to wear when I was menstruating. The Messenger of Allah (ﷺ) said: 'Are you menstruating?' I said: 'Yes.' Then he called me and I lied down with him under the blanket."
