Sayyida Fatimah bint Abi Hubaysh (may Allah be pleased with her) narrates that she was afflicted with istihada (non-menstrual bleeding). The Prophet Muhammad (peace be upon him) said to her: "When the blood of menstruation comes, it will be more. When that situation occurs, then stop performing prayers. But when it is the other situation, then perform ablution and offer prayers, because this is blood from another vein."
