Good Manners and Form (Al-Adab)
Bukhari :: Book 8 :: Volume 73 :: Hadith 216
Narrated Jabir bin 'Abdullah Al-Ansari:
Allah's Apostle said, "Name yourselves after me (by my name) but do not call (yourselves) by my Kuniya (1), for I am Al-Qasim (distributor), and I distribute among you Allah's blessings." This narration has also come on the authority of Anas that the ! Prophet said so."
