سنن أبي داود

Sa'id b. Musayyab told that his father said on the authority of his grandfather (Hazn): The Prophet (ﷺ) asked: What is your name? He replied: Hazn (rugged). He said: You are Sahl (smooth). He said: No, smooth is trodden upon and disgraced. Sa'id said: I then thought that ruggedness would remain among us after it.

AbuDawud said: The Prophet (ﷺ) changed the names al-'As, Aziz, Atalah, Shaytan, al-Hakam, Ghurab, Hubab, and Shihab and called him Hisham. He changed the name Harb (war) and called him Silm (peace). He changed the name al-Munba'ith (one who lies) and called him al-Mudtaji' (one who stands up). He changed the name of a land Afrah (barren) and called it Khadrah (green). He changed the name Shi'b ad-Dalalah (the mountain path of a stray), the name of a mountain path and called it Shi'b al-Huda (mountain path of guidance). He changed the name Banu az-Zinyah (children of fornication) and called them Banu ar-Rushdah (children of those who are on the right path), and changed the name Banu Mughwiyah (children of a woman who allures and goes astray), and called them Banu Rushdah (children of a woman who is on the right path).

AbuDawud said: I omitted the chains of these for the sake of brevity.
