وَعَن عائشةَ قَالَتْ: جَاءَ أَعْرَابِيٌّ إِلَى النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَ: أَتُقَبِّلُونَ الصِّبْيَانَ؟ فَمَا نُقَبِّلُهُمْ. فَقَالَ النَّبِي صلى الله عَلَيْهِ وَسلم: «أوَ أملكُ لَكَ أَنْ نَزَعَ اللَّهُ مِنْ قَلْبِكَ الرَّحْمَةَ» . مُتَّفق عَلَيْهِ
Aisha (may Allah be pleased with her) narrates: A Bedouin came to the Prophet (peace and blessings of Allah be upon him) and asked, "Do you kiss children? For we do not kiss them." The Prophet (peace and blessings of Allah be upon him) replied, "I have no control over you if Allah has removed mercy from your heart (that I could bring it back)." Agreed upon.
