The Prohibition Of Taking The Kunyah Abul-Qasim, And The Names Which Are Recommended
Sahih Muslim
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا وَكِيعٌ، عَنِ الأَعْمَشِ، ح وَحَدَّثَنِي أَبُو سَعِيدٍ، الأَشَجُّ حَدَّثَنَا وَكِيعٌ، حَدَّثَنَا الأَعْمَشُ، عَنْ سَالِمِ بْنِ أَبِي الْجَعْدِ، عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " تَسَمَّوْا بِاسْمِي وَلاَ تَكَنَّوْا بِكُنْيَتِي فَإِنِّي أَنَا أَبُو الْقَاسِمِ أَقْسِمُ بَيْنَكُمْ " . وَفِي رِوَايَةِ أَبِي بَكْرٍ " وَلاَ تَكْتَنُوا " .
Jabir b. Abdullah reported Allah's Messenger (ﷺ) as saying: Give the name after my name, but do not give (the kunya of Abu'l-Qasim after my) kunya, for I am Abu'l-Qasim (in the sense) that I distribute amongst you (the spoils of war) and disseminate the knowledge (of revelation). This hadith has been transmitted on the authority of Abu Bakr but with a slight variation of wording.
