Indeed, the men who practice charity and the women who practice charity and [they who] have loaned Allah a goodly loan - it will be multiplied for them, and they will have a noble reward.
-Quran 57:18
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.
-Quran 2:261
