´It was narrated from 'Umar ibn Al-Khattab that the Prophet(ﷺ) said:` "If I live- if Allah wills - I will forbid the names Rabah(profit), Najih(saved), Aflah (Successful), Nafi (beneficial) and Yasar(prosperity)."
In one hadith, the reasoning for this prohibition has been stated: because you will say, “Is he present here?” If he is not there, then (the one answering) will say, “No.” (Sahih Muslim) The meaning is that if someone asks, “Is Nafi‘ (Beneficial) in the house?” and in response it is said, “He is not present,” it is as if you have said that there is no beneficial person in the house, all are useless. Even though this may not be the speaker’s intention, outwardly it becomes an inappropriate statement. Therefore, giving such names is disliked (makruh), but not forbidden (haram).
'Abdullah bin 'Umar reported: While we were sitting with the Messenger of Allah (ﷺ) , a person, one of the Ansar, came to him and greeted him. The Ansari then turned back. Upon this the Messenger of Allah (ﷺ) said: O brother of Ansar, how is my brother Sa'd bin 'Ubadah? He said: He is better. The Messenger of Allah (ﷺ) said: Who amongst you would visit him? He (the Holy Prophet) stood up and we also got up along with him, and we were more than ten persons. We had neither shoes with us, nor socks, nor caps, nor shirts. We walked on the barren land till we came to him. The people around him kept away till the Messenger of Allah (ﷺ) and his Companions with him came near him (Sa'd bin 'Ubadah).

Narrated Jabir ibn Abdullah: 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-Amash 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.

Benefits and Issues: One should specifically avoid the aforementioned names. And it is mentioned in Sahih Muslim that later the Prophet (sallallahu alayhi wa sallam) remained silent about this. (Sahih Muslim, Al-Adab, Chapter: Dislike of Naming with Certain Names and with Nafi’ and the Like, Hadith: 2138)
