Narrated Al-Bara:
حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ ، أَخْبَرَنَا شُعْبَةُ ، عَنْ عَدِيِّ بْنِ ثَابِتٍ ، قَالَ سَمِعْتُ الْبَرَاءَ ، قَالَ لَمَّا مَاتَ إِبْرَاهِيمُ ـ عَلَيْهِ السَّلاَمُ ـ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " إِنَّ لَهُ مُرْضِعًا فِي الْجَنَّةِ " .
When Ibrahim (the son of the Prophet) died, Allah's Messenger (ﷺ) said, "There is a wet nurse for him in Paradise."
