Narrated Jabir:
حَدَّثَنَا مُحَمَّدُ بْنُ كَثِيرٍ ، أَخْبَرَنَا شُعْبَةُ ، عَنْ مَنْصُورٍ ، عَنْ سَالِمٍ ، عَنْ جَابِرٍ ـ رضى الله عنه ـ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " تَسَمَّوْا بِاسْمِي، وَلاَ تَكْتَنُوا بِكُنْيَتِي "
The Prophet (ﷺ) said, "Name yourselves after me, but do not call yourselves by my Kuniya."
