Muhammad ibn al-Muthanna narrated to us, Mu'adh ibn Hisham narrated to us, my father narrated to me, on the authority of Yahya ibn Abi Kathir, who said: Abu Salamah ibn 'Abd al-Rahman narrated to us that Zaynab bint Umm Salamah told him that Umm Salamah told her, saying: While I was lying down with the Messenger of Allah, peace and blessings be upon him, under a woolen coverlet, I began to menstruate, so I slipped away and took my menstrual garments. The Messenger of Allah, peace and blessings be upon him, said to me, "Have you begun menstruating?" I said, "Yes." So he called me, and I lay down with him under the coverlet. She said: She and the Messenger of Allah, peace and blessings be upon him, used to perform the major ritual purification (ghusl) from janabah in a single vessel.
