Al-Adab Al-Mufrad, Book 34, Hadith 837 (English) ⓘ

Anas ibn Malik said, "The Prophet, may Allah bless him and grant him peace, was in the market when a man said, 'Abu'l-Qasim!' The Prophet, may Allah bless him and grant him peace, turned towards him. He said, 'Messenger of Allah, I was calling this man.' The Prophet, may Allah bless him and grant him peace, said, 'Call yourselves with my name but do no use my kunya.'"

حَدَّثَنَا آدَمُ، قَالَ‏:‏ حَدَّثَنَا شُعْبَةُ، عَنْ حُمَيْدٍ الطَّوِيلِ، عَنْ أَنَسِ بْنِ مَالِكٍ قَالَ‏:‏ كَانَ النَّبِيُّ صلى الله عليه وسلم فِي السُّوقِ، فَقَالَ رَجُلٌ‏:‏ يَا أَبَا الْقَاسِمِ، فَالْتَفَتَ إِلَيْهِ النَّبِيُّ صلى الله عليه وسلم، فَقَالَ‏:‏ يَا رَسُولَ اللهِ، إِنَّمَا دَعَوْتُ هَذَا، فَقَالَ النَّبِيُّ صلى الله عليه وسلم‏:‏ سَمُّوا بِاسْمِي، وَلاَ تُكَنُّوا بِكُنْيَتِي‏.‏
