Sahih al-Bukhari, Volume 7, Book 62, Hadith 143 (USC-MSA) ⓘ
Narrated `Aisha: Whenever Allah's Messenger finished his `Asr prayer, he would enter upon his wives and stay with one of them. One day he went to Hafsa and stayed with her longer than usual.
حَدَّثَنَا فَرْوَةُ، حَدَّثَنَا عَلِيُّ بْنُ مُسْهِرٍ، عَنْ هِشَامٍ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم إِذَا انْصَرَفَ مِنَ الْعَصْرِ دَخَلَ عَلَى نِسَائِهِ، فَيَدْنُو مِنْ إِحْدَاهُنَّ، فَدَخَلَ عَلَى حَفْصَةَ، فَاحْتَبَسَ أَكْثَرَ مَا كَانَ يَحْتَبِسُ.
