Charity (zakat and sadaqah) purifies wealth and helps the less fortunate, earning immense rewards in the Hereafter: “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.” (Quran, Al-Baqarah 2:261)
