Musannaf Ibn Abi Shaybah

Hazrat Sha'bi says that I sent my wife to the wife of Hazrat Masruq to ask her about the woman experiencing istihada (non-menstrual bleeding). The wife of Hazrat Masruq reported that Hazrat Aisha (may Allah be pleased with her) said that the woman experiencing istihada should not pray during the days of menstruation, then she should perform ghusl (ritual bath) and make a new ablution (wudu) for every prayer.
