Good Manners and Form (Al-Adab)

Bukhari :: Book 8 :: Volume 73 :: Hadith 217

Narrated Abu Huraira:

The Prophet said, "Name yourselves after me (by my name), but do not call yourselves by my Kuniya, and whoever sees me in a dream, he surely sees me, for Satan cannot impersonate me (appear in my figure). And whoever intentionally ascribes something to me falsely, he will surely take his place in the (Hell) Fire.
