Sahih Muslim Book - 43, Hadith - 6026

حَدَّثَنَا زُهَيْرُ بْنُ حَرْبٍ ، وَمُحَمَّدُ بْنُ عَبْدِ اللهِ بْنِ نُمَيْرٍ ، وَاللَّفْظُ لِزُهَيْرٍ ، قَالاَ : حَدَّثَنَا إِسْمَاعِيلُ ، وَهُوَ ابْنُ عُلَيَّةَ ، عَنْ أَيُّوبَ ، عَنْ عَمْرِو بْنِ سَعِيدٍ ، عَنْ أَنَسِ بْنِ مَالِكٍ ، قَالَ : مَا رَأَيْتُ أَحَدًا كَانَ أَرْحَمَ بِالْعِيَالِ مِنْ رَسُولِ اللهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، قَالَ : كَانَ إِبْرَاهِيمُ مُسْتَرْضِعًا لَهُ فِي عَوَالِي الْمَدِينَةِ ، فَكَانَ يَنْطَلِقُ وَنَحْنُ مَعَهُ , فَيَدْخُلُ الْبَيْتَ وَإِنَّهُ لَيُدَّخَنُ ، وَكَانَ ظِئْرُهُ قَيْنًا ، فَيَأْخُذُهُ فَيُقَبِّلُهُ ، ثُمَّ يَرْجِعُ. قَالَ عَمْرٌو : فَلَمَّا تُوُفِّيَ إِبْرَاهِيمُ قَالَ رَسُولُ اللهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : إِنَّ إِبْرَاهِيمَ ابْنِي , وَإِنَّهُ مَاتَ فِي الثَّدْيِ , وَإِنَّ لَهُ لَظِئْرَيْنِ تُكَمِّلاَنِ رَضَاعَهُ فِي الْجَنَّةِ.

It was narrated that Anas bin Malik said: “I have never seen anyone who was more compassionate towards children than the Messenger of Allah (s.a.w). Ibrahim (the son of the Prophet (s.a.w)) was sent to be nursed in the suburbs of Al-Madinah. He used to go, and we would go with him, and he would enter the house which was filled with smoke, as his foster father was blacksmith, and he would hold him and kiss him, then he would come back.” ‘Amr said: “When Ibrahim died, the Messenger of Allah (s.a.w) said: ‘Ibrahim is my son and he had died infancy. He has two foster-mothers who will complete his suckling in Paradise.”
