(21) CHAPTER. Sleeping with a menstruating woman (one’s wife) while she is wearing her clothes (that are worn during menses).
322. Narrated Zainab bint ‘Abi Salama : Umm Salama said, “I got my menses while I was lying with the Prophet, peace be upon him, under a woolen sheet. So I slipped away, took the clothes for menses and put them on. Allah’s Messenger, peace be upon him, said, ‘Have you got your menses?’ I replied, ‘Yes.’ Then he called me and took me with him under the woolen sheet.”
Umm Salama further said, “The Prophet, peace be upon him, used to kiss me while he was observing Saum (fasting). The Prophet, peace be upon him, and I used to take the bath of Janaba from a single pot.”
