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.

And if you were to harm (them) in retaliation, harm them to the measure you were harmed. And if you opt for patience, it is definitely much better for those who are patient.
