باب مَنْ سَمَّى بِأَسْمَاءِ الأَنْبِيَاءِ
Sahih al-Bukhari 6194

Narrated Isma`il:

I asked Abi `Aufa, "Did you see Ibrahim, the son of the Prophet (ﷺ) ?" He said, "Yes, but he died in his early childhood. Had there been a Prophet after Muhammad then his son would have lived, but there is no Prophet after him."

حَدَّثَنَا ابْنُ نُمَيْرٍ، حَدَّثَنَا مُحَمَّدُ بْنُ بِشْرٍ، حَدَّثَنَا إِسْمَاعِيلُ، قُلْتُ لاِبْنِ أَبِي أَوْفَى رَأَيْتَ إِبْرَاهِيمَ ابْنَ النَّبِيِّ صلى الله عليه وسلم قَالَ مَاتَ صَغِيرًا، وَلَوْ قُضِيَ أَنْ يَكُونَ بَعْدَ مُحَمَّدٍ صلى الله عليه وسلم نَبِيٌّ عَاشَ ابْنُهُ، وَلَكِنْ لاَ نَبِيَّ بَعْدَهُ‏.‏
