Yahya related to me from Malik from Abu'n-Nadr, the mawla of Umar ibn Ubaydullah that A'isha bint Talha told him that she was once with A'isha, the wife of the Prophet, may Allah bless him and grant him peace, and her husband, who was fasting, came and visited her there. (He was Abdullah ibn Abd ar-Rahman ibn Abi Bakras-Siddiq.) A'isha said to him, "What's stopping you from coming close to your wife and kissing her and joking with her?" He said, "Can I kiss her when I am fasting?" She said, "Yes."


وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ أَبِي النَّضْرِ، مَوْلَى عُمَرَ بْنِ عُبَيْدِ اللَّهِ أَنَّ عَائِشَةَ بِنْتَ طَلْحَةَ، أَخْبَرَتْهُ أَنَّهَا، كَانَتْ عِنْدَ عَائِشَةَ زَوْجِ النَّبِيِّ صلى الله عليه وسلم فَدَخَلَ عَلَيْهَا زَوْجُهَا هُنَالِكَ وَهُوَ عَبْدُ اللَّهِ بْنُ عَبْدِ الرَّحْمَنِ بْنِ أَبِي بَكْرٍ الصِّدِّيقِ وَهُوَ صَائِمٌ فَقَالَتْ لَهُ عَائِشَةُ مَا يَمْنَعُكَ أَنْ تَدْنُوَ مِنْ أَهْلِكَ فَتُقَبِّلَهَا وَتُلاَعِبَهَا فَقَالَ أُقَبِّلُهَا وَأَنَا صَائِمٌ قَالَتْ نَعَمْ ‏.‏
