Lady Aisha Siddiqa (may Allah be pleased with her) narrates: Fatimah bint Abu Hubaysh came to the service of the Prophet Muhammad (peace be upon him). She said: O Messenger of Allah! I suffer from continuous bleeding for one or two months. The Prophet Muhammad (peace be upon him) said: This is not menstruation, rather it is blood from some other vein. When menstruation comes, then during those specific days in which you used to have your period before, leave the prayer, and when those days pass, then perform ghusl and do wudu for every prayer.
