43. Good Conduct and Manners
٤٣۔ كتاب الأدب
The Prophet ﷺ said: If anyone is called by my name, he must not be given my kunyah (surname), and if anyone uses my kunyah (surname), he must not be called by my name. Abu Dawud said: Ibn 'Ajlan transmitted it to the same effect from his father on the authority if Abu Hurairah. It has also been transmitted by Abu Zar'ah from Abu Hurairah in two different versions. And similar is the version of 'Abd al-Rahman b. Abi 'Amrah from Abu Hurairah. This version is disputed: Al-Thawri and Ibn Juraij transmitted it according to the version of Abu al-Zubair; and Ma'qil b. 'Ubaid Allah transmitted it according to the version of Ibn Sirin. It is again dispted on Musa b. Yasar from Abu Hurariah, transmitting it in two versions: Hammad b. Khalid and Ibn Abi Fudaik varied in their versions.
أَنَّ النَّبِيَّ ﷺ قَالَ مَنْ تَسَمَّى بِاسْمِي فَلاَ يَكْتَنِي بِكُنْيَتِي وَمَنْ تَكَنَّى بِكُنْيَتِي فَلاَ يَتَسَمَّى بِاسْمِي
