General Behavior (Kitab Al-Adab)
Dawud :: Book 41 : Hadith 4942
Narrated Jabir ibn Abdullah:
The Prophet (peace_be_upon_him) said: If I survive (God willing), I shall forbid my people to give the names Nafi' (beneficial), Aflah (successful) and Barakah (blessing). Al-A'mash said: I do not know whether he mentioned Nafi' or not. When a man comes and asks: Is there Barakah (blessing)? The people say: No.
