BE AFFECTIONATE TO YOUR CHILDREN H H 226 The Prophet, praise and peace be upon him, kissed his grandson Hasan, the son of Ali. Aqr'a the son of Habis was with them at that time and said: 'I have ten sons and have never kissed any of them.' The Prophet, praise and peace be upon him, looked at him and said: 'He who has no compassion will receive none.'" R 226 Bukhari and Muslim with a chain up to Abu Hurairah who related this.
225- وعن أَبي هريرة رضي الله عنه ، قَالَ : قَبَّلَ النَّبيُّ صلى الله عليه وآله وسلم الحَسَنَ بْنَ عَليٍّ رضي الله عنهما ، وَعِنْدَهُ الأَقْرَعُ بْنُ حَابِس ، فَقَالَ الأقْرَعُ : إن لِي عَشرَةً مِنَ الوَلَدِ مَا قَبَّلْتُ مِنْهُمْ أحَداً . فَنَظَرَ إِلَيْهِ رَسُول الله صلى الله عليه وآله وسلم ، فَقَالَ : "مَنْ لا يَرْحَمْ لاَ يُرْحَمْ !" مُتَّفَقٌ عَلَيهِ .
