And do not make mischief in the earth after its reformation, and call on Him fearing and hoping; surely the mercy of Allah is nigh to those who do good (to others).

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.
