The Messenger of Allah ﷺ said, "Name yourselves after my name, but do not take my kunya, for I am Abu Qasim, I distribute among you." In Abu Bakr's version the wording is, "and do not adopt my kunya." He also said, "I have only been made a distributor, apportioning among you."
و حدثنا أبو كريب حدثنا أبو معاوية عن الأعمش بهذا الإسناد وقال إنما جعلت قاسما أقسم بينكم
