Hadith: When Ibrahīm died, the Messenger of Allah (may Allah's peace and blessings be upon him) said: There is a wet nurse for him in Paradise

عن البراء رضي الله عنه قال: لما تُوفِّي إبراهيم -عليه السلام-، قال رسول الله صلى الله عليه وسلم : «إنَّ له مُرْضِعًا في الجنة».
[صحيح] - [رواه البخاري]

Al-Barā' (may Allah be pleased with him) reported: When Ibrahīm died, the Messenger of Allah (may Allah's peace and blessings be upon him) said: "There is a wet nurse for him in Paradise."
Sahih/Authentic. - [Al-Bukhari]

Explanation

Ibrahīm, the son of the Messenger of Allah (may Allah's peace and blessings be upon him) from Māriyah the Copt, died when he was eighteen months old. So the Prophet (may Allah's peace and blessings be upon him) informed us that Allah, the Almighty, had prepared someone in Paradise to breastfeed him until his suckling period would be completed.
