Sahih al-Bukhari 5250
Sahih al-Bukhari · Book 67: Wedlock, Marriage (Nikaah) · The man's poking his daughter in the flank while admonishing her
Narrated `Aisha:
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ ، أَخْبَرَنَا مَالِكٌ ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ الْقَاسِمِ ، عَنْ أَبِيهِ ، عَنْ عَائِشَةَ ، قَالَتْ عَاتَبَنِي أَبُو بَكْرٍ وَجَعَلَ يَطْعُنُنِي بِيَدِهِ فِي خَاصِرَتِي فَلاَ يَمْنَعُنِي مِنَ التَّحَرُّكِ إِلاَّ مَكَانُ رَسُولِ اللَّهِ صلى الله عليه وسلم وَرَأْسُهُ عَلَى فَخِذِي.
Abu Bakr admonished me and poked me with his hands in the flank, and nothing stopped me from moving at that time except the position of Allah's Messenger (ﷺ) whose head was on my thigh.
