Hadith 6:1255
Waki’ narrated to us, from Isma’il, from al-Sha’bi, who said: The Messenger of Allah (may Allah bless him and grant him peace) said: "He has a wet nurse in Paradise who will complete the remainder of his breastfeeding," meaning Ibrahim.
حدثنا وكيع عن إسماعيل عن الشعبي قال قال رسول الله صلى الله عليه وسلم ان له مرضعا في الجنة تتم بقية رضاعته يعني إبراهيم
