Sayyida Umm Salama (may Allah be pleased with her)'s brother, 'Amir bin Abu Umayyah, narrates that Sayyida Umm Salama informed him: The Prophet (peace and blessings of Allah be upon him) would be in a state of janabah at the time of true dawn, then he would fast. (The narrator says) So Sayyiduna Abu Hurairah (may Allah be pleased with him) rejected this person's statement.
