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.
