Narrated Aishah, Ummul Muminin: A woman had a prolonged flow of blood in the time of the Messenger of Allah ﷺ. She was commanded to advance the afternoon prayer and delay the noon prayer, and to take a bath for them only once; and to delay the sunset prayer and advance the night prayer and to take a bath only once for them; and to take a bath separately for the dawn prayer. I (Shubah) asked Abdur Rahman: (Is it) from the Prophet ﷺ? I do not report to you anything except from the Prophet ﷺ.

Narrated Hamnah daughter of Jahsh: Hamnah said my menstruation was great in quantity and severe. So I came to the Messenger of Allah ﷺ for a decision and told him. I found him in the house of my sister, Zaynab, daughter of Jahsh. I said: Messenger of Allah, I am a woman who menstruates in great quantity and it is severe, so what do you think about it? It has prevented me from praying and fasting. He said: I suggest that you should use cotton, for it absorbs the blood. She replied: It is too copious for that. He said: Then take a cloth. She replied: It is too copious for that, for my blood keeps flowing. The Messenger of Allah ﷺ said: I shall give you two commands; whichever of them you follow, that will be sufficient for you without the other, but you know best whether you are strong enough to follow both of them. He added: This is a stroke of the Devil, so observe your menses for six or seven days, Allah alone knows which it should be; then wash. And when you see that you are purified and quite clean, pray during twenty-three or twenty-four days and nights and fast, for that will be enough for you, and do so every month, just as women menstruate and are purified at the time of their menstruation and their purification. But if you are strong enough to delay the noon (Zuhr) prayer and advance the afternoon (Asr) prayer, to wash, and then combine the noon and the afternoon prayer; to delay the sunset prayer and advance the night prayer, to wash, and then combine the two prayers, do so: and to wash at dawn, do so: and fast if you are able to do so if possible. The Messenger of Allah ﷺ said: Of the two commands this is more to my liking. 1 Abu Dawud said: Amr bin Thabit narrated from Ibn Aqil: Hamnah said: Of the two commands this is the one which is more to my liking. 2 In this version these words were not quoted as the statement of the Prophet ﷺ; it gives it as a statement of Hamnah. Abu Dawud said: Amr bin Thabit was a Rafidi. This has been said by Yahya bin Main. Abu Dawud said: I heard Ahmad (b. Hanbal) say: I am doubtful about the tradition transmitted by Ibn Aqil.

Narrated Aishah, Ummul Muminin: Sahlah daughter of Suhayl had a prolonged flow of blood. She came to the Prophet ﷺ. He commanded her to take a bath for every prayer. When it became hard for her, he commanded her to combine the noon and afternoon prayers with one bath and the sunset and night prayer with one bath, and to take a bath (separately) for the dawn prayer. Abu Dawud said: Ibn Uyainah reported from Abdur-Rahman bin al-Qasim on the authority of his father, saying: A woman had a prolonged flow of blood. She asked the Prophet ﷺ. He commanded her to the same effect.

Asma daughter of Unais said: I said: Messenger of Allah, Fatimah daughter of Abu Hubaish had a flow of blood for a certain period and did not pray. The Messenger of Allah ﷺ said: Glory be to Allah! This comes from the devil. She should sit in a tub, and when she sees yellowness of the top of the water, she would take a bath once for the Zuhr and Asr prayer, and take another bath for the Maghrib and 'Isha prayers, and take a bath once for the fajr prayer, and in between times she would perform ablution. Abu Dawud said: Mujahid reported on the authority of Ibn Abbas: When bathing became hard for her, he commanded her to combine the two prayers. Abu Dawud said: Ibrahim reported it from Ibn Abbas. This is also the view of Ibrahim al-Nakha'i and Abdullah bin Shaddad.
