(1) باب النَّهْىِ عَنِ التَّكَنِّي، بِأَبِي الْقَاسِمِ وَبَيَانِ مَا يُسْتَحَبُّ مِنَ الأَسْمَاءِ .
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.
