Sunan Ibn Majah, hadith 1687

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 ‏.‏

It was narrated that Ibrahim said:“Al-Aswad and Masruq entered upon ‘Aishah and said: ‘Did the Messenger of Allah (ﷺ) 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.’”
