Quran 2:182 — The Heifer (Al-Baqarah)

If one sees gross injustice or bias on the part of a testator, and takes corrective action to restore justice to the will, he commits no sin. GOD is Forgiver, Most Merciful.

[2:181] If anyone alters a will he had heard, the sin of altering befalls those responsible for such altering. GOD is Hearer, Knower.

[2:183] O you who believe, fasting is decreed for you, as it was decreed for those before you, that you may attain salvation.
