Hadith 10:9
Abu Bakr narrated to us, he said: Ibn Idris narrated to us, from Layth, from Tawus, who said: If he divorces her during a period of purity in which he has had intercourse with her, she does not count that menstrual period as part of her waiting period.
حدثنا أبو بكر قال نا بن إدريس عن ليث عن طاوس قال إذا طلقها في طهر قد جامعها فيه لم تعتد فيه بتلك الحيضة
