Mishkat al-Masabih 521

Hamna daughter of Jahsh said that her menstruation was great in quantity and severe, so she went to the Prophet for a decision and told him. She found him in the house of her sister Zainab daughter of Jahsh and said, “Messenger of God, I menstruate to a great extent, and it is severe, so what command do you give me about it? It has prevented me from praying and fasting.” He said, “I suggest that you use cotton, for it removes the blood.” She replied, “It is too copious for that.” He said, “Then stop it with a tight rag.” 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.” So the Prophet said, “I shall give you two commands; whichever of them you follow, it will make the other unnecessary, but you will know best whether you are strong enough to follow both of them This is a stroke of the devil, so observe your menses for six or seven days, God alone knowing 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 prayer and advance the afternoon prayer, then wash and combine the noon and the afternoon prayer; to delay the sunset prayer and advance the night prayer, then wash and combine the two prayers, do so; and to wash at drawn, do so; and fast if you are able.” God’s messenger said, “This is the one which is more attractive to me.”

Ahmad, Abu Dawud and Tirmidhi transmitted it.

‘Adi b. Thabit quoted his father as saying that his grandfather (‘Adi's grandfather’s name is given as Dinar by Yahya b. Ma'in) reported the Prophet as saying regarding a woman who has a prolonged flow of blood that she should abandon prayer during as many days as she used to have her courses, then wash, perform ablution for every prayer, fast and pray.

Tirmidhi and Abu Dawud transmitted it.

Umm Salama said that in the time of God’s messenger there was a woman who had an issue of blood, so Umm Salama asked the Prophet to give a decision about her. He said, “She should consider the number of nights and days during which she used to menstruate each month before she was afflicted with this trouble and abandon prayer during that period each month; then when she finishes that she should wash, tie a cloth over her private parts and pray.”

Malik, Abu Dawud and Darimi transmitted it, and Nasa’i transmitted something to the same effect;
