Have you not seen those to whom a portion of the Book has been given? They believe in idols and false deities and say of those who disbelieve: These are better guided in the path than those who believe.

And certainly Allah made a covenant with the children of Israel, and We raised up among them twelve chieftains; and Allah said: Surely I am with you; if you keep up prayer and pay the poor-rate and believe in My messengers and assist them and offer to Allah a goodly gift, I will most certainly cover your evil deeds, and I will most certainly cause you to enter into gardens beneath which rivers flow, but whoever disbelieves from among you after that, he indeed shall lose the right way.

O you who believe! whoever from among you turns back from his religion, then Allah will bring a people, He shall love them and they shall love Him, lowly before the believers, mighty against the unbelievers, they shall strive hard in Allah's way and shall not fear the censure of any censurer; this is Allah's Face, He gives it to whom He pleases, and Allah is Ample-giving, Knowing.
