Hadith 43:450
Sahih (Al-Albani)
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.
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ سَالِمٍ، حَدَّثَنَا إِبْرَاهِيمُ بْنُ يُوسُفَ، عَنْ أَبِيهِ، عَنْ أَبِي إِسْحَاقَ، عَنِ الْبَرَاءِ، قَالَ دَخَلْتُ مَعَ أَبِي بَكْرٍ أَوَّلَ مَا قَدِمَ الْمَدِينَةَ فَإِذَا عَائِشَةُ ابْنَتُهُ مُضْطَجِعَةٌ قَدْ أَصَابَتْهَا حُمَّى فَأَتَاهَا أَبُو بَكْرٍ فَقَالَ لَهَا كَيْفَ أَنْتِ يَا بُنَيَّةُ وَقَبَّلَ خَدَّهَا
