حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا الْمُعْتَمِرُ، عَنْ إِيَاسِ بْنِ دَغْفَلٍ، قَالَ رَأَيْتُ أَبَا نَضْرَةَ قَبَّلَ خَدَّ الْحَسَنِ بْنِ عَلِيٍّ عَلَيْهِمَا السَّلاَمُ ‏.‏
Translation
Narrated Al-Bara' ibn Azib

I went in with AbuBakr when he had newly come to Medina and he found his daughter Aisha lying down afflicted with fever. AbuBakr went to her, and saying: How are you, girlie? kissed her on the cheek.
