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