It is narrated from Sayyidah Aishah (may Allah be pleased with her) that Fatimah (may Allah be pleased with her) came to the Prophet (peace and blessings be upon him) and said: O Messenger of Allah, I am a woman with istihadah. The Prophet (peace and blessings be upon him) said: "That is a vein. Wait for the days of your menstruation; when they have passed, perform ghusl, bind a cloth, and perform ablution for prayer."
