"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.'" (Using translation from Ibn Mājah 3737)
أَنَّ رَسُولَ اللهِ ﷺ كَانَ بِالْبَقِيعِ فَنَادَى رَجُلٌ يَا أَبَا الْقَاسِمِ فَالْتَفَتَ إِلَيْهِ فَقَالَ لَمْ أَعْنِكَ قَالَ تَسَمَّوْا بِاسْمِي وَلَا تَكَنَّوْا بِكُنْيَتِي
