The Aposlte of Allah (May peace be upon him) forbade giving four names to our slaves : Aflah (successful), Yasar (wealth), Naf(beneficial) and Rabah (profit).
Sunan Abi Dawud Book 43, Hadith 187
← Previous Hadith Do not call your servant Yasar (wealth), Rabah (profit), Nijih(prosperous) and Aflah (successful), for you may ask; Is he there? And someone says: No. Samurah said: These are four (names), so do not attribute more to me.

Sunan Abi Dawud Book 43, Hadith 186 Next Hadith → The Prophet (ﷺ) 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.

Abu Dawud said: A similar tradition has been transmitted by Abu al-Zubair on the authority of Jabir from the Prophet (ﷺ) through a different chain of narrators. This version has no mention of Barakah.
