حَدَّثَنِي عَلِيُّ بْنُ حُجْرٍ، حَدَّثَنَا سُفْيَانُ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، - رضى الله عنها - قَالَتْ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يُقَبِّلُ إِحْدَى نِسَائِهِ وَهُوَ صَائِمٌ . ثُمَّ تَضْحَكُ .
'A'isha (Allah be pleased with her) said that the Messenger of Allah (ﷺ) kissed one of his wives while he was fasting, and then she ('A'isha) smiled (as she narrated).
