Hadith 10:28
Abu Bakr narrated to us, he said: Abd al-Wahhab al-Thaqafi narrated to us, from Ubayd Allah ibn Umar, from Nafi, from Ibn Umar, regarding the one who divorces his wife while she is menstruating: He said: "Do not count that menstruation."
حدثنا أبو بكر قال نا عبد الوهاب الثقفي عن عبيد الله بن عمر عن نافع عن بن عمر في الذي يطلق امرأته وهي حائض قال لا تعتد بتلك الحيضة
