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.

And Musa said: My Lord knows best who comes with guidance from Him, and whose shall be the good end of the abode; surely the unjust shall not be successful.
