Many of the followers of the Book wish that they could turn you back into unbelievers after your faith, out of envy from themselves, (even) after the truth has become manifest to them; but pardon and forgive, so that Allah should bring about His command; surely Allah has power over all things.

And Allah sets forth a parable of two men; one of them is dumb, not able to do anything, and he is a burden to his master; wherever he sends him, he brings no good; can he be held equal with him who enjoins what is just, and he (himself) is on the right path?
