(15) باب رَحْمَتِهِ صلى الله عليه وسلم الصِّبْيَانَ وَالْعِيَالَ وَتَوَاضُعِهِ وَفَضْلِ ذَلِكَ
Abu Huraira reported that al-Aqra' b. Habis saw Allah's Apostle (ﷺ) kissing Hasan. He said:
I have ten children, but I have never kissed any one of them, whereupon Allah's Messenger (ﷺ) said: He who does not show mercy (towards his children), no mercy would be shown to him.
