Hadith 10:71
Abu Bakr narrated to us, he said: Abu Usama narrated to us, from Hisham, who said: Muhammad was asked about a man who divorces his wife three times in one sitting. He said: "I do not see any harm in that. Abd al-Rahman ibn Awf divorced his wife three times, and it was not considered a fault against him."
حدثنا أبو بكر قال نا أبو أسامة عن هشام قال سئل محمد عن الرجل يطلق امرأته ثلاثا في مقعد واحد قال لا أعلم بذلك بأسا قد طلق عبد الرحمن بن عوف امرأته ثلاثا فلم يعب عليه ذلك
