One Should Donate (Zakat)
Surah Al-Baqra-2
Verse no. 261: - Those who spend their wealth (money) in the way of Allah, the example of their expense is like sowing a grain. Seven stems grow out of it, and each stem has a hundred grains. In this way, Allah grants growth to those whose deeds he prefers. He is all-Encompassing as well as Omniscient.
Verse no. 262: - Those who spend their wealth (money) in the way of Allah and then do not follow up what they have spent with reminders of it, nor do they cause sorrow, their reward is with their Lord and there is no chance for any grief (worry) and fear. (That is, they do not need to worry or fear. God protects them. He also increases their wealth.)
