AbuSalamah said: Zaynab daughter of AbuSalamah reported to me that a woman had a copious flow of blood. She was the wife of AbdurRahman ibn Awf. The Messenger of Allah (ﷺ) commanded her to take a bath at the time of every prayer, and then to pray. He reported to me that Umm Bakr told him that Aisha said: The Messenger of Allah (ﷺ) said about a woman who was doubtful of her menstruation after purification that it was a vein or veins.

Abu Dawud said: The two commands (of which the Prophet gave option) were as follows in the version reported by Ibn 'Aqil: He said: If you are strong enough, then take a bath for every prayer; otherwise combine the (two prayers), as al-Qasim reported in his version. This statement was also narrated by Sa'id b. Jubair from 'Ali and Ibn 'Abbas.
