We will not allow you to give the name after the name of Messenger of Allah ﷺ until you ask him (the Holy Prophet). So he (that person) came and said (to the Holy Prophet): A child was born in my house and I wanted to give him the name (of Muhammad) after the name of Messenger of Allah, whereas my people did not allow me that I should name him after that (sacred) name until I have asked Allah's Apostle ﷺ in this connection, whereupon he said: Give him the name after my name, but do not call him by my kunya, for I have been sent as a Qasim as I distribute amongst you.  

وُلِدَ لِرَجُلٍ مِنَّا غُلاَمٌ فَسَمَّاهُ مُحَمَّدًا فَقُلْنَا لاَ نَكْنِيكَ بِرَسُولِ اللَّهِ ﷺ حَتَّى تَسْتَأْمِرَهُ قَالَ فَأَتَاهُ فَقَالَ إِنَّهُ وُلِدَ لِي غُلاَمٌ فَسَمَّيْتُهُ بِرَسُولِ اللَّهِ وَإِنَّ قَوْمِي أَبَوْا أَنْ يَكْنُونِي بِهِ حَتَّى تَسْتَأْذِنَ النَّبِيَّ ﷺ فَقَالَ سَمُّوا بِاسْمِي وَلاَ تَكَنَّوْا بِكُنْيَتِي فَإِنَّمَا بُعِثْتُ قَاسِمًا أَقْسِمُ بَيْنَكُمْ  

The Ansar have done well to give the name (to your children) after my name, but do not give them the kunya after my kunya.  

أَنَّ رَجُلاً مِنَ الأَنْصَارِ وُلِدَ لَهُ غُلاَمٌ فَأَرَادَ أَنْ يُسَمِّيَهُ مُحَمَّدًا فَأَتَى النَّبِيَّ ﷺ فَسَأَلَهُ فَقَالَ أَحْسَنَتِ الأَنْصَارُ سَمُّوا بِاسْمِي وَلاَ تَكْتَنُوا بِكُنْيَتِي  

The Ansar have done well to give the name (to your children) after my name, but do not give them the kunya after my kunya. (Using translation from Muslim 2133f)  

أَنَّ رَجُلًا مِنَ الْأَنْصَارِ وُلِدَ لَهُ غُلَامٌ فَأَرَادَ أَنْ يُسَمِّيَهُ مُحَمَّدًا فَأَتَى النَّبِيَّ ﷺ فَسَأَلَهُ فَقَالَ أَحْسَنَتِ الْأَنْصَارُ تَسَمَّوْا بِاسْمِي وَلَا تَكَنَّوْا بِكُنْيَتِي  

[Machine] A man from the Ansar had a son and he wanted to name him Muhammad. However, it seemed that they disliked it. So, he carried him on his shoulder and went to the Messenger of Allah ﷺ. The Messenger of Allah ﷺ said, "Name yourselves after me, but do not use my kunya."  

أَنَّ رَجُلًا مِنَ الْأَنْصَارِ وُلِدَ لَهُ غُلَامٌ فَأَرَادَ أَنْ يُسَمِّيَهُ مُحَمَّدًا فَكَأَنَّهُمْ كَرِهُوهُ فَحَمَلَهُ عَلَى عَاتِقِهِ فَأَتَى بِهِ رَسُولَ اللهِ ﷺ فَقَالَ رَسُولُ اللهِ ﷺ تَسَمَّوْا بِاسْمِي وَلَا تَكَنَّوْا بِكُنْيَتِي  

[Machine] A boy was born to one of us, and his father named him Al-Qasim. We said, "We won't offer congratulations until we ask the Prophet ﷺ ." So, we mentioned it to him, and he said, "Name him after me, but do not call him by my nickname, for I have been sent as a distributer (Qasim) among you."  

وُلِدَ لِرَجُلٍ مِنَّا غُلَامٌ فَسَمَّاهُ الْقَاسِمَ فَقُلْنَا لَا نُكَنِّيكَ بِهِ حَتَّى نَسْأَلَ النَّبِيَّ ﷺ فَذَكَرْنَا لَهُ فَقَالَ تَسَمَّوْا بِاسْمِي وَلَا تَكْتَنُوا بِكُنْيَتِي فَإِنَّمَا بُعِثْتُ قَاسِمًا بَيْنَكُمْ  

[Machine] "To name him Muhammad and they came with him the Messenger of Allah, peace be upon him, and he said, "The Ansar have done well to name themselves after me and not use my nickname, for I was sent as a distributor [of inheritance] among you."  

أَنْ يُسَمُّوهُ مُحَمَّدًا فَأَتَوْا بِهِ رَسُولَ اللَّهِ ﷺ فَقَالَ «أَحْسَنَتِ الْأَنْصَارُ تَسَمَّوْا بِاسْمِي وَلَا تَكْتَنُوا بِكُنْيَتِي فَإِنَّمَا بُعِثْتُ قَاسِمًا أَقْسِمُ بَيْنَكُمْ»
