Hadith 512250
Chapter 29: Divorce - كتاب الطلاق
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ نَافِعٍ، أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، طَلَّقَ امْرَأَةً لَهُ فِي مَسْكَنِ حَفْصَةَ زَوْجِ النَّبِيِّ صلى الله عليه وسلم وَكَانَ طَرِيقَهُ إِلَى الْمَسْجِدِ فَكَانَ يَسْلُكُ الطَّرِيقَ الأُخْرَى مِنْ أَدْبَارِ الْبُيُوتِ كَرَاهِيَةَ أَنْ يَسْتَأْذِنَ عَلَيْهَا حَتَّى رَاجَعَهَا .
Yahya related to me from Malik from Nafi that Abdullah ibn Umar divorced one of his wives in the house of Hafsa, the wife of the Prophet, may Allah bless him and grant him peace, while he was on the way to the mosque. He went another route from behind the houses being averse to ask permission to enter until he returned to her.
