While the Prophet ﷺ was in the market, a man called (somebody), "O Abu-l-Qasim!' The Prophet ﷺ turned to him and said "Name yourselves after me but do not call yourselves by my Kuniya."  

كَانَ النَّبِيُّ ﷺ فِي السُّوقِ فَقَالَ رَجُلٌ يَا أَبَا الْقَاسِمِ فَالْتَفَتَ النَّبِيُّ ﷺ فَقَالَ سَمُّوا بِاسْمِي وَلاَ تَكْتَنُوا بِكُنْيَتِي  

The Prophet ﷺ said, "Name yourselves after me, but do not call yourselves by my Kuniya."  

عَنِ النَّبِيِّ ﷺ قَالَ تَسَمَّوْا بِاسْمِي وَلاَ تَكْتَنُوا بِكُنْيَتِي  

Abu-l-Qasim said, "Name yourselves after me, but do not call yourselves by my Kuniya."  

أَبُو الْقَاسِمِ ﷺ سَمُّوا بِاسْمِي وَلاَ تَكْتَنُوا بِكُنْيَتِي
