Sahih Muslim Book - 38, Hadith - 5589

حَدَّثَنَا هَنَّادُ بْنُ السَّرِيِّ ، حَدَّثَنَا عَبْثَرٌ ، عَنْ حُصَيْنٍ ، عَنْ سَالِمِ بْنِ أَبِي الْجَعْدِ ، عَنْ جَابِرِ بْنِ عَبْدِ اللهِ ، قَالَ : وُلِدَ لِرَجُلٍ مِنَّا غُلاَمٌ ، فَسَمَّاهُ مُحَمَّدًا فَقُلْنَا : لاَ نَكْنِكَ بِرَسُولِ اللهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، حَتَّى تَسْتَأْمِرَهُ ، قَالَ فَأَتَاهُ ، فَقَالَ : إِنَّهُ وُلِدَ لِي غُلاَمٌ فَسَمَّيْتُهُ بِرَسُولِ اللهِ , وَإِنَّ قَوْمِي أَبَوْا أَنْ يَكْنُونِي بِهِ حَتَّى تَسْتَأْذِنَ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، فَقَالَ : سَمُّوا بِاسْمِي ، وَلاَ تَكَنَّوْا بِكُنْيَتِي ، فَإِنَّمَا بُعِثْتُ قَاسِمًا أَقْسِمُ بَيْنَكُمْ.

It was narrated that Jabir bin 'Abdullah said: "A boy was born to a man among us and he called him Muhammad. We said: 'We will not allow you to call him by the name of the Messenger of Allah (s.a.w) until you consult him.' So he went to him and said: 'A boy has been born to me and I called him after the Messenger of Allah, but my people refused to call me after him (i.e., Abu Muhammad) until I ask permission from the Prophet (s.a.w).' He (s.a.w) said: 'You may call yourselves by my name but not my Kunyah, for I have only been sent as a Qasim (distributor), I distribute (Allah's blessings) among you."'
