And of them there are some who listen to you; but We have set veils on their hearts, so they understand it not, and deafness in their ears; if they see every one of the Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.) they will not believe therein; to the point that when they come to you to argue with you, the disbelievers say: "These are nothing but tales of the men of old."

Invite (mankind, O Muhammad ﷺ) to the Way of your Lord (i.e. Islam) with wisdom (i.e. with the Divine Inspiration and the Quran) and fair preaching, and argue with them in a way that is better. Truly, your Lord knows best who has gone astray from His Path, and He is the Best Aware of those who are guided.

And if they argue with you (as regards the slaughtering of the sacrifices), say; "Allah knows best of what you do.

And argue not on behalf of those who deceive themselves. Verily, Allah does not like anyone who is a betrayer of his trust, and indulges in crime.

Lo! You are those who have argued for them in the life of this world, but who will argue for them on the Day of Resurrection against Allah, or who will then be their defender?
