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.

Do not make excuses; you have denied indeed after you had believed; if We pardon a party of you, We will chastise (another) party because they are guilty.
