278. Commandment to be not thou a disputer for the faithless

[4:106] We have surely sent down to thee the Book comprising the truth, that thou mayest judge between men by that which Allah has taught thee. And be not thou a disputer for the faithless;

[4:108] And plead not on behalf of those who are dishonest to themselves. Surely, Allah loves not one who is perfidious and a great sinner.
