Lady Aisha (may Allah be pleased with her) narrates that Fatimah bint Abu Hubaysh came to the Messenger of Allah (peace and blessings be upon him) and said, "I am a woman who suffers from Istihada (non-menstrual bleeding), so I do not remain pure. Should I stop praying?" He said, "No, that is only a vein (bleeding), not menstruation. So when your menstruation comes, leave the prayer, and when those days pass, wash the blood from your body and clothes, then pray. Then perform ablution for every prayer until the (menstruation) time returns."
