Anas bin Malik reported,

I have never seen anyone more compassionate toward children than the Messenger of Allah ﷺ. Ibrahim had a wet-nurse in the highlands of Medina, and the Prophet ﷺ would go to visit him with us along. He would enter the house, which was filled with smoke since the wet-nurse's husband was a blacksmith. He would take Ibrahim, kiss him, and then return.Amr said, when Ibrahim died, the Messenger of Allah ﷺ said, "Ibrahim is my son, and he died while still nursing. He has two wet-nurses who will complete his nursing in Paradise."

عن أنس بن مالك قال

ما رأيت أحدا كان أرحم بالعيال من رسول الله ﷺ قال كان إبراهيم مسترضعا له في عوالي المدينة فكان ينطلق ونحن معه فيدخل البيت وإنه ليدخن وكان ظئره قينا فيأخذه فيقبله ثم يرجع قال عمرو فلما توفي إبراهيم قال رسول الله ﷺ إن إبراهيم ابني وإنه مات في الثدي وإن له لظئرين تكملان رضاعه في الجنة
