It was narrated that Anas said:
"The Messenger of Allah(ﷺ) was in Baqi', and a man called out to another man: 'O Abul-Qasim!' The Messenger of Allah(ﷺ) turned to him, and he said: 'I didn't mean you.' The Messenger of Allah(ﷺ) said: 'Call yourselves by my name but do not call yourselves by my Kunyah.'"
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا عَبْدُ الْوَهَّابِ الثَّقَفِيُّ، عَنْ حُمَيْدٍ، عَنْ أَنَسٍ، قَالَ كَانَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ بِالْبَقِيعِ فَنَادَى رَجُلٌ رَجُلاً يَا أَبَا الْقَاسِمِ فَالْتَفَتَ إِلَيْهِ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ فَقَالَ إِنِّي لَمْ أَعْنِكَ . فَقَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ
" تَسَمَّوْا بِاسْمِي وَلاَ تَكْتَنُوا بِكُنْيَتِي "
