عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ الْأَنْصَارِيِّ رَضِيَ اللَّهُ عَنْهُمَا أَنَّ رَجُلًا مِنَ الْأَنْصَارِ وُلِدَ لَهُ غُلَامٌ فَأَرَادَ أَنْ يُسَمِّيَهُ مُحَمَّدًا فَأَتَى النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فَسَأَلَهُ فَقَالَ أَحْسَنَتِ الْأَنْصَارُ تَسَمَّوْا بِاسْمِي وَلَا تَكَنَّوْا بِكُنْيَتِي
It is narrated from Sayyiduna Jabir bin Abdullah Ansari (may Allah be pleased with him) that a boy was born to an Ansari. He wanted to name him Muhammad, so he came to the Noble Prophet (peace and blessings be upon him) and asked him. The Prophet (peace and blessings be upon him) said: The Ansar have done well; name him with my name, but do not use my kunya.
