Is this a Hadith?
“And if a person reviles you and dishonours you with what he knows of you then do not degrade him (back) with what you know of him for the curse (of abuse) will only be upon him.”
Yes, this is a reliable Hadith recorded in Sunan Abi Dawud and other Hadith collections as part of a longer Hadith.
Sayyiduna Jabir ibn Sulaym (radiyallahu ‘anhu) reports that Rasulullah (sallallahu ‘alayhi wa sallam) said: “…If any person reviles or insults you for something which he finds in you then do not insult him with what you know of him, for he will bear the evil consequences of it.”
(Sunan Abi Dawud, Hadith: 4081 and Sahih Ibn Hibban, Hadith: 521)
