I asked Abi ʿAufa, "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 إِسْمَاعِيلُ قُلْتُ لاِبْنِ أَبِي أَوْفَى رَأَيْتَ إِبْرَاهِيمَ ابْنَ النَّبِيِّ ﷺ قَالَ مَاتَ صَغِيرًا وَلَوْ قُضِيَ أَنْ يَكُونَ بَعْدَ مُحَمَّدٍ ﷺ نَبِيٌّ عَاشَ ابْنُهُ وَلَكِنْ لاَ نَبِيَّ بَعْدَهُ  

“I said to ‘Abdullah bin Abi Awfa: ‘Did you see Ibrahim, the son of the Messenger of Allah ﷺ?’ He said: ‘He died when he was small, and if it had been decreed that there should be any Prophet after Muhammad ﷺ, his son would have lived. But there is no Prophet after him.’”  

قُلْتُ لِعَبْدِ اللَّهِ بْنِ أَبِي أَوْفَى رَأَيْتَ إِبْرَاهِيمَ ابْنَ رَسُولِ اللَّهِ ﷺ قَالَ مَاتَ وَهُوَ صَغِيرٌ وَلَوْ قُضِيَ أَنْ يَكُونَ بَعْدَ مُحَمَّدٍ ﷺ نَبِيٌّ لَعَاشَ ابْنُهُ وَلَكِنْ لاَ نَبِيَّ بَعْدَهُ
