Charity in the Quran

The Best Investment [2:261] The example of those who spend their monies in the cause of GOD is that of a grain that produces seven spikes, with a hundred grains in each spike. GOD multiplies this manifold for whomever He wills. GOD is Bounteous, Knower. Charity [2:265] The example of those who give their money seeking GOD's pleasure, out of sincere conviction, is that of a garden on high fertile soil; when heavy rain falls, it gives twice as much crop. If heavy rain is not available, a drizzle will suffice. GOD is Seer of everything you do. What to Give [2:267] O you who believe, you shall give to charity from the good things you earn, and from what we have produced for you from the earth. Do not pick out the bad therein to give away, when you yourselves do not accept it unless your eyes are closed. You should know that GOD is Rich, Praiseworthy.
