The Iron - 57:10 What is wrong with you that you spend not in the way of Allah, while to Allah belongs the riches of the heavens and the earth. Those of you who spend and fight before the victory are not equal to those who spend and fight afterwards; they are superior to them. Allah has promised salvation to every one of them. Allah is aware of all that you do.
