The opposite party of the above mentioned fair and honest people, are some faithless oppressors that are described in this verse and the next one.
``As for the unbelievers neither their wealth nor their children will avail them aught against Allah.''
Their false spending for false purposes, will avail them nothing because the very essence of charity is faith and love. If the wealth is spent for sheer ostentation, or hunting people by the snare of the giver's power by a pretence of charity, how can one expect a good result and productive farmland by that?
Qurän clearly announces that social power and financial advantages, alone, bring no points in the sight of God, and relying on them is a mere mistake; unless they are used in a correct way.
