Musannaf Ibn Abi Shaybah 1362 — What a woman with irregular bleeding

Al-Qa'qa' bin Hakim said: "I asked Sa'id bin al-Musayyib about the woman with istihadah, and he said: 'No one knows more about this than I do. When her menstruation comes, she should leave the prayer, and when the menstruation goes, she should take a ritual bath, wash off the blood, and perform ablution for every prayer.'"
