Sunan Ibn Majah, Chapter: The Chapters on Dry Ablution

that she experienced prolonged non-menstrual bleeding during the time of the Messenger of Allah (saw). She came to the Messenger of Allah (saw) and said: "I am suffering prolonged and painful bleeding." He said: "Fill it with a pad of cloth." She said: "It is worse than that, it is flowing copiously." He said: "Then bind yourself with a cloth and observe your menses for six or seven days, in the knowledge of Allah, then have a bath and perform prayer and fast for twenty-three or twenty-four days. Delay Zuhr and bring 'Asr forward, and take (one) bath for both, and delay Maghrib and bring 'Isha forward, and have (one) bath for both. This is what I prefer of the two matters.'" (Da'if)
