"The Messenger of Allah (ﷺ) would fondle one of his wives when she was menstruating, if she wore and Izar (waist wrap) that reached halfway down her thighs or to her knees.
Sunan an-Nasa'i Book 3, Hadith 28
← Previous Hadith "I entered upon 'Aishah with my mother and maternal aunt, and we asked her what the Prophet (ﷺ) used to do when one of (his wives) was menstruating. She said: He would tell us, when when of us menstruated, to wrap a wide Izar around herself then he would embrace her chest and breasts.

Sunan an-Nasa'i Book 3, Hadith 27 Next Hadith → "Can a woman eat with her husband while she is menstruating?' She said: 'Yes. The Messenger of Allah (ﷺ) would call me to eat with him while I was menstruating. He would take a piece of bone on which some bits of meat were left and insist that I take it first, so I would nibble a little from it, then put it down. Then he would take it and nibble from it, and he would put his mouth where mine had been on the bone. Then he would call for a drink and insist that I take it first before he drank from it. So I would take it and drink from it, then put it down, then he would take it and drink from it, putting his mouth where mine had been on the cup.'"
