Quran 2:159 — The Heifer (Al-Baqarah)

Those who conceal our revelations and guidance, after proclaiming them for the people in the scripture, are condemned by GOD; they are condemned by all the condemners.

[2:158] The knolls of Safa and Marwah are among the rites decreed by GOD. Anyone who observes Hajj or 'Umrah commits no error by traversing the distance between them. If one volunteers more righteous works, then GOD is Appreciative, Omniscient.

[2:160] As for those who repent, reform, and proclaim, I redeem them. I am the Redeemer, Most Merciful.
