Surah Al-Mu'minun 23:96

ٱدْفَعْ بِٱلَّتِى هِىَ أَحْسَنُ ٱلسَّيِّئَةَ ۚ نَحْنُ أَعْلَمُ بِمَا يَصِفُونَ

Repel, by [means of] what is best, [their] evil. We are most knowing of what they describe.

Translation: Saheeh International

Tafsir

Ward off with that which is better that is to say with the better trait of pardoning and shunning them the evil act the hurt they cause you — this was revealed before the command to fight them. We know best what they allege what they invent of lies and what they say and so We will requite them for it.
