‘A'isha told of Fatima daughter of Abu Hubaish coming to the Prophet and saying, “I am a woman whose blood keeps flowing, and I am never purified; Shall I therefore abandon prayer?” He replied, “No that is only a vein and is not menstruation; so when your menstrua
tion comes on abandon prayer, and when it ends wash the blood from yourself and then pray.”
‘Urwa b. az-Zubair reported from Fatima daughter of Abu Hubaish that her blood kept flowing, so the Prophet said to her, “When the blood of the menses comes it is black blood which can be recognised, so when that comes refrain from prayer; but when a different type comes perform ablution any pray, for it is due only to a vein.”
Zaid b. Aslam said that a man asked God’s messenger what was lawful for him in his wife when she was menstruating, and he replied,
“She should tie her waist-wrapper on her, then you can do what you like above it.”
