Herein is enshrined a Divine principle; His Retribution is determined by the kind of things done by man. A proverb may be quoted to this effect, "As you sow, so shall you reap". If we spend a lot in the way of Allah, He will also recompense us a lot. And if we stint spending in His way, He will dispense sustenance to us with restrain, too. If we accumulate wealth in a miserly fashion and avoid spending it in the way of Allah, He will also restrain the flow of His bounty to us. To sum up, the Hadith inspires us to generously spend money in the way of Allah and also sternly warns us of the consequences of stinginess and parsimony.
