What is wrong with you that you do not spend money for charity to please your Lord? Are you afraid of poverty while you are pleasing the One Who owns the whole wealth of the universe and is the One Who provides you with wealth at first place? Do not you know that you can not take anything with you and that God eventually will inherit whatever you were afraid to spend a part of with to please Him? Those of you who spend a part of their money in charity before becoming rich and fight before victory are not equal to those who spend a part of their money after becoming rich and show their willingness in fight after victory! Although both are entitled to the reward, yet the formers are necessarily higher in rank than the latter. God is aware of whatever you do (and sees who has performed what deeds, under what kind of circumstances, and with what intention).
