(15) باب رَحْمَتِهِ صلى الله عليه وسلم الصِّبْيَانَ وَالْعِيَالَ وَتَوَاضُعِهِ وَفَضْلِ ذَلِكَ
Anas b. Malik reported:
I have never seen anyone more kind to one's family than Allah's Messenger (ﷺ), and Ibrahim was sent to the suburb of Medina for suckling. He used to go there and we accompanied him. He entered the house, and it was filled with smoke as his foster-father was a bricksmith. He took him (his son Ibrihim) and kissed him and then came back. 'Amr said that when Ibrihim died. Allah's LMessenger (ﷺ) said: Ibrihim is my son and he dies as a suckling babe. He has now two foster-mothers who would complete his suckling period in Paradise.
