كتاب الصيام
18  
Fasting

Yahya related to me from Malik from Hisham ibn Urwa from his father that A'isha, umm al-muminin, may Allah be pleased with her, said, "The Messenger of Allah, may Allah bless him and grant him peace, used to kiss certain of his wives when fasting," and then she laughed.

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ أُمِّ الْمُؤْمِنِينَ، - رضى الله عنها - أَنَّهَا قَالَتْ إِنْ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم لَيُقَبِّلُ بَعْضَ أَزْوَاجِهِ وَهُوَ صَائِمٌ ‏.‏ ثُمَّ ضَحِكَتْ ‏.‏
