It is narrated from Sayyida Asma bint Abi Bakr (may Allah be pleased with her) that a woman asked the Messenger of Allah (peace and blessings be upon him): O Messenger of Allah! Tell me, if menstrual blood gets on any of our clothes, what should she do? The Messenger of Allah (peace and blessings be upon him) said: "If menstrual blood gets on any of your clothes, she should scrape it off, then pour water over it so that she can pray in it."
