And He it is Who has made you successors in the land and raised some of you above others by (various) grades, that He might try you by what He has given you; surely your Lord is quick to requite (evil), and He is most surely the Forgiving, the Merciful.

And what reason have you that you should not spend in Allah's way? And Allah's is the inheritance of the heavens and the earth, not alike among you are those who spent before the victory and fought (and those who did not): they are more exalted in rank than those who spent and fought afterwards; and Allah has promised good to all; and Allah is Aware of what you do.
