What did the Prophet Muhammad (peace be upon him) say about using his Kuniya for naming purposes?
 Narrated Jabi:                     A man among us begot a boy whom he named Al-Qasim. The people said, "We will not call him (i.e., the father) by that Kuniya (Abu-l-Qasim) till we ask the Prophet about it. The Prophet said. "Name yourselves by my name, but do not call (yourselves) by my Kuniya."
