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 even if there were a Quran with which the mountains were made to pass away, or the earth were travelled over with it, or the dead were made to speak thereby; nay! the commandment is wholly Allah's, Have not yet those who believe known that if Allah please He would certainly guide all the people? And (as for) those who disbelieve, there will not cease to afflict them because of what they do a repelling calamity, or it will alight close by their abodes, until the promise of Allah comes about; surely Allah will not fail in (His) promise.

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?
