Sunan Ibn Majah, Volume 2, Book 7, Hadith 1687 (DarusSalam) ⓘ
It was narrated that Ibrahim said: “Al-Aswad and Masruq entered upon ‘Aishah and said: ‘Did the Messenger of Allah touch (his wife) when he was fasting?’ She said: ‘He used to do that, and he was the strongest of all of you in controlling his desire.’”
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا إِسْمَاعِيلُ ابْنُ عُلَيَّةَ، عَنِ ابْنِ عَوْنٍ، عَنْ إِبْرَاهِيمَ، قَالَ دَخَلَ الأَسْوَدُ وَمَسْرُوقٌ عَلَى عَائِشَةَ فَقَالاَ أَكَانَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ يُبَاشِرُ وَهُوَ صَائِمٌ قَالَتْ كَانَ يَفْعَلُ وَكَانَ أَمْلَكَكُمْ لإِرْبِهِ .
