Increase your Wealth
“The parable of those who spend their substance in the way of Allah is that of a grain of corn: It grows seven ears and each ear has a hundred grains. Allah gives manifold increase to whom He pleases and Allah cares for all and He knows all things.” (2:261)
Reaping Continous Rewards Even after Death
“When a man dies, his acts come to an end, but three, recurring charity, or knowledge (by which people) benefit, or a pious son, who prays for him (for the deceased)” [Muslim].
Multiply Your Rewards
“The example of those who spend their wealth in the way of Allah is like a seed [of grain] which grows seven spikes; in each spike is a hundred grains. And Allah multiplies [His reward] for whom He wills. And Allah is all-Encompassing and Knowing.”
Expiation of Sins
“If you disclose your charity, it is well; but if you conceal it and give it to the poor, that is better for you. [Allah] will expiate some of your sins. And Allah is well-acquainted with all that you do.” (Surah al-Baqarah:271)
