Narrated 'Ali bin Abi Talib:
حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ ، حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ الْقَطَّانُ ، حَدَّثَنَا فِطْرُ بْنُ خَلِيفَةَ ، حَدَّثَنِي مُنْذِرٌ، وَهُوَ الثَّوْرِيُّ عَنْ مُحَمَّدِ ابْنِ الْحَنَفِيَّةِ ، عَنْ عَلِيِّ بْنِ أَبِي طَالِبٍ ، أَنَّهُ قَالَ يَا رَسُولَ اللَّهِ أَرَأَيْتَ إِنْ وُلِدَ لِي بَعْدَكَ أُسَمِّيهِ مُحَمَّدًا وَأُكْنِيهِ بِكُنْيَتِكَ قَالَ " نَعَمْ " . قَالَ فَكَانَتْ رُخْصَةً لِي . هَذَا حَدِيثٌ صَحِيحٌ .
that he said: "O Messenger of Allah (ﷺ)! If I have a son after you do you think I could name him your Kunyah?" He said: "Yes." So he said: "So that was permitted for me."
