Ya-Sin 47
And when it is said to them, “Spend from that which Allah has provided for you,” those who disbelieve say to those who believe,”Should we feed one whom, if Allah had willed, He would have fed? You are not but in clear error.”
Charity in the Qur’an
Al-Baqarah 261
The example of those who spend their wealth in the way of Allah is like a grain which grows seven spikes; in each spike is a hundred grains. And Allah multiplies for whom He wills. And Allah is All-Encompassing and Knowing.
