Verily, Ibrahīm is my son and he died as a suckling infant, and, verily, he has two wet nurses in Paradise completing his suckling period
Authentic hadithعن أنس بن مالك رضي الله عنه قال: «ما رأيتُ أحدا كان أرحم بالعِيال من رسول الله صلى الله عليه وسلم »، قال: «كان إبراهيم مُسْتَرضَعًا له في عَوَالي المدينة، فكان ينطلق ونحن معه، فيدخل البيت وإنه ليُدَخَّن، وكان ظِئْره قَيْنًا، فيأخذه فيُقبِّله، ثم يرجع». قال عمرو: فلما تُوفي إبراهيم قال رسول الله صلى الله عليه وسلم : «إن إبراهيم ابني، وإنه مات في الثَّدي، وإن له لظِئْرين تُكمِلان رضاعه في الجنة».
Anas ibn Mālik (may Allah be pleased with him) reported: I have never seen anyone more merciful to children than the Messenger of Allah (may Allah's peace and blessings be upon him). (His son) Ibrahīm was sent to a wet nurse on the outskirts of Madīnah. So he used to go there, and we would accompany him, and he would enter the house, which was filled with smoke for Ibrahīm's foster father was a blacksmith, and he would take Ibrahīm and kiss him then return." ‘Amr said: "When Ibrahīm died, the Messenger of Allah (may Allah's peace and blessings be upon him) said: 'Ibrahīm is my son, and he died as a suckling infant, and, verily, he has two wet nurses in Paradise completing his suckling period.'"
Explanation
Anas ibn Mālik (may Allah be pleased with him) reported that he had never seen anyone more merciful to children than the Messenger of Allah (may Allah's peace and blessings be upon him). His son, Ibrahīm, was suckled by a wet nurse living in the suburb of Madīnah. Hence, he used to go there with some of his Companions to visit his son. He used to enter the house that would be filled with smoke because the wet nurse's husband was a blacksmith. He would take Ibrahīm, kiss him and then return home. On Ibrahīm's death, the Messenger of Allah (may Allah's peace and blessings be upon him) said: Ibrahīm is my son, and he died as a suckling infant, and he has two wet nurses in Paradise to complete his suckling period until he reaches the age of two. Ibrahīm died when he was sixteen or seventeen months old. So, he was to be suckled until completing the suckling period, which is two years according to what is stated in the Qur'an. This was done to honor the Prophet (may Allah's peace and blessings be upon him) and his son.
