Muhammad had intercourse while fasting

وَحَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا أَبُو عَاصِمٍ، قَالَ سَمِعْتُ ابْنَ عَوْنٍ، عَنْ إِبْرَاهِيمَ، عَنِ الأَسْوَدِ، قَالَ انْطَلَقْتُ أَنَا وَمَسْرُوقٌ، إِلَى عَائِشَةَ - رضى الله عنها - فَقُلْنَا لَهَا أَكَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يُبَاشِرُ وَهُوَ صَائِمٌ قَالَتْ نَعَمْ وَلَكِنَّهُ كَانَ أَمْلَكَكُمْ لإِرْبِهِ أَوْ مِنْ أَمْلَكِكُمْ لإِرْبِهِ ‏.‏ شَكَّ أَبُو عَاصِمٍ ‏.‏

Aswad reported: I and Masruq went to 'A'isha (Allah be pleased with her) and asked her if the Messenger of Allah (ﷺ) had intercourse (his wives) while fasting. She said: Yes; but he had the greatest control over his organs among you: or he was one of those who had control over his organs.
