Sunan Abi Dawud, Hadith 5119 ⓘ
Narrated Abdullah ibn Umar: A woman was my wife and I loved her, but Umar hated her. He said to me: Divorce her, but I refused. Umar then went to the Prophet and mentioned that to him. The Prophet said: Divorce her.
حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَحْيَى، عَنِ ابْنِ أَبِي ذِئْبٍ، قَالَ حَدَّثَنِي خَالِي الْحَارِثُ، عَنْ حَمْزَةَ بْنِ عَبْدِ اللَّهِ بْنِ عُمَرَ، عَنْ أَبِيهِ، قَالَ كَانَتْ تَحْتِي امْرَأَةٌ وَكُنْتُ أُحِبُّهَا وَكَانَ عُمَرُ يَكْرَهُهَا فَقَالَ لِي طَلِّقْهَا فَأَبَيْتُ فَأَتَى عُمَرُ النَّبِيَّ صلى الله عليه وسلم فَذَكَرَ ذَلِكَ لَهُ فَقَالَ النَّبِيُّ صلى الله عليه وسلم " طَلِّقْهَا " .
