Quran 57:29 — Iron (Al-Hadeed)

Thus, the followers of previous scripture should know that they have not monopolized GOD's mercy and grace, and that all grace is in GOD's hand. He bestows it upon whomever He wills. GOD is Possessor of Infinite Grace.

[57:28] O you who believe, you shall reverence GOD and believe in His messenger. He will then grant you double the reward from His mercy, endow you with light to guide you, and forgive you. GOD is Forgiver, Most Merciful.
