Lady Asma bint Umais (may Allah be pleased with her) narrates: I said, "O Messenger of Allah! Fatimah bint Abi Hubaysh has been suffering from prolonged bleeding (istihada) for a long time." The Prophet (peace and blessings be upon him) said: "Glory be to Allah! This is from Shaytan. She should sit in a large vessel." When the woman sat in it, the yellowness of her menstrual blood became predominant. Then the Prophet (peace and blessings be upon him) said: "She should perform ghusl once for Zuhr and Asr, and once for Maghrib and Isha, then perform a separate ghusl for Fajr, and perform wudu in between."
