Sunan Ibn Majah, Book 1, Hadith 541 (In-Book) ⓘ
'Urwah bin Az-Subair narrated from 'Aishah, that: The Messenger of Allah kissed one of his women (i.e., wives), then he went to perform the prayer, and he did not perform ablution. I ('Urwah bin Zubair) said: "That was not anyone but you,' and she smiled."
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَعَلِيُّ بْنُ مُحَمَّدٍ، قَالاَ حَدَّثَنَا وَكِيعٌ، حَدَّثَنَا الأَعْمَشُ، عَنْ حَبِيبِ بْنِ أَبِي ثَابِتٍ، عَنْ عُرْوَةَ بْنِ الزُّبَيْرِ، عَنْ عَائِشَةَ، أَنَّ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ قَبَّلَ بَعْضَ نِسَائِهِ ثُمَّ خَرَجَ إِلَى الصَّلاَةِ وَلَمْ يَتَوَضَّأْ . قُلْتُ مَا هِيَ إِلاَّ أَنْتِ . فَضَحِكَتْ .
