An-Nahl 16:125

OdAAu ila sabeeli rabbika bilhikmatiwalmawAAithati alhasanati wajadilhumbillatee hiya ahsanu inna rabbaka huwa aAAlamubiman dalla AAan sabeelihi wahuwa aAAlamu bilmuhtadeen

Invite to the way of your Lord with wisdom and good instruction, and argue with them in a way that is best. Indeed, your Lord is most knowing of who has strayed from His way, and He is most knowing of who is [rightly] guided.

Invite (people) to the way of your Lord with wisdom and good counsel. And argue with them in the best of manners. Surely, your Lord knows best the one who deviates from His way, and He knows best the ones who are on the right path.
