Quran 2:262 — The Heifer (Al-Baqarah)

Those who spend their money in the cause of GOD, then do not follow their charity with insult or harm, will receive their recompense from their Lord; they have nothing to fear, nor will they grieve.

[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.

[2:263] Kind words and compassion are better than a charity that is followed by insult. GOD is Rich, Clement.
