'A'isha reported:They (some Companions of the Holy Prophet) were conversing with one another in the presence of the Messenger of Allah (ﷺ) (during his last) illness. Umm Salama and Umm Habiba made a mention of the church and then (the hadith was) narrated.
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَعَمْرٌو النَّاقِدُ، قَالاَ حَدَّثَنَا وَكِيعٌ، حَدَّثَنَا هِشَامُ بْنُ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، أَنَّهُمْ تَذَاكَرُوا عِنْدَ رَسُولِ اللَّهِ صلى الله عليه وسلم فِي مَرَضِهِ فَذَكَرَتْ أُمُّ سَلَمَةَ وَأُمُّ حَبِيبَةَ كَنِيسَةً . ثُمَّ ذَكَرَ نَحْوَهُ .
