Al-Mu'minun 23:96
ٱدْفَعْ بِٱلَّتِى هِىَ أَحْسَنُ ٱلسَّيِّئَةَ ۚ نَحْنُ أَعْلَمُ بِمَا يَصِفُونَ
IdfaAA billatee hiya ahsanu assayyi-atanahnu aAAlamu bima yasifoon
"Repel, by [means of] what is best, [their] evil. We are most knowing of what they describe."
Al-Mu'minun 23:96, translation by Sahih International
A short reflection
Repel evil by that which is better. We are most knowing of what they describe.
