This verse raises a question that: ``What wrong or evil would happen to them, had they believed in Allah and the Last Day, and gave in charity or alms a part or some of the sustenance that Allah has given them?'' Sustenance may mean, material, spiritual or intellectual provisions or anything that pertains to our life and growth. And of course, all these means and provisions are from God, and we must spent or use them for God. Such expenditure is not a waste or burden, but rather a positive response to our inner most natural demands, which finally may lead to our salvation and prosperity.
