And his wealth was destroyed; so he began to wring his hands for what he had spent on it, while it lay, having fallen down upon its roofs, and he said: Ah me! would that I had not associated anyone with my Lord.

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.
