Quran 2:270 — The Heifer (Al-Baqarah)

Any charity you give, or a charitable pledge you fulfill, GOD is fully aware thereof. As for the wicked, they will have no helpers.

[2:269] He bestows wisdom upon whomever He chooses, and whoever attains wisdom, has attained a great bounty. Only those who possess intelligence will take heed.

[2:271] If you declare your charities, they are still good. But if you keep them anonymous, and give them to the poor, it is better for you, and remits more of your sins. GOD is fully Cognizant of everything you do.
