It was narrated from Mu'awiyah bin Abu Sufyan that :
He asked Umm Habibah, the wife of the Prophet: "What did you used to do with the Messenger of Allah when you were menstruating?" She said: "If it was at the beginning of the period when the bleeding is heavy, we would tie the waist-wrapper tightly around our thighs, then lie down with the Messenger of Allah." (IT)
