Hadith 10:463
Abu Bakr narrated to us, he said: Abd al-Wahhab narrated to us, from Sa'id, from Mutarrif, from Humayd ibn Hilal, from Sa'd ibn Hisham, that Zayd ibn Thabit said: "It is three [divorces]; it is not lawful for him until she marries a husband other than him."
حدثنا أبو بكر قال نا عبد الوهاب عن سعيد عن مطرف عن حميد بن هلال عن سعد بن هشام أن زيد بن ثابت قال هي ثلاث لا تحل له حتى تنكح زوجا غيره
