Surely the (true) religion with Allah is Islam, and those to whom the Book had been given did not show opposition but after knowledge had come to them, out of envy among themselves; and whoever disbelieves in the communications of Allah then surely Allah is quick in reckoning.

And do not believe but in him who follows your religion. Say: Surely the (true) guidance is the guidance of Allah-- that one may be given (by Him) the like of what you were given; or they would contend with you by an argument before your Lord. Say: Surely grace is in the hand of Allah, He gives it to whom He pleases; and Allah is Ample-giving, Knowing.

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.

But if they repent and keep up prayer and pay the poor-rate, they are your brethren in faith; and We make the communications clear for a people who know.
