The example of those who give in charity and its reward 2:261-262
2:261 The example of those who give their wealth in the way of Allah is like a grain of corn that sprouts seven ears, in every ear a hundred grains. Allah multiplies to whom He will, Allah is the Embracer, the Knower.
2:262 Those who spend their wealth in the way of Allah and do not follow their spending with reproach and insults shall be rewarded by their Lord; they shall have nothing to fear or to regret.
