sahih

'A'isha reported:

We took 'Abdullah b. Zubair to Allah's Messenger (ﷺ) so that he should put saliva in his mouth and we had to make a good deal of effort in order to procure them.

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا أَبُو خَالِدٍ الأَحْمَرُ، عَنْ هِشَامٍ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، قَالَتْ جِئْنَا بِعَبْدِ اللَّهِ بْنِ الزُّبَيْرِ إِلَى النَّبِيِّ صلى الله عليه وسلم يُحَنِّكُهُ فَطَلَبْنَا تَمْرَةً فَعَزَّ عَلَيْنَا طَلَبُهَا ‏.‏
