What prevents us from spending money for the benefits of other needy people?

 

Verses 16-18 of Chapter 64:
Therefore, fear Allah as far as you can, and listen and obey and spend your wealth : this is for your own good. And those who are saved from the greed of their own hearts, are truly successful. If you lend to Allah a goodly loan, He will pay you back manifold and will forgive you your faults. Allah is Appreciative and Forbearing. He knows the open and the hidden. He is the All-Mighty, the All-Wise.
