Quran 57:19 — Iron (Al-Hadeed)

Those who believed in GOD and His messengers are the saints and martyrs. Reserved for them at their Lord are their rewards and their light. As for those who disbelieved and rejected our revelations, they have incurred Hell.

[57:18] Surely, the charitable men and women have loaned GOD a loan of goodness. They will receive their reward multiplied manifold; they have deserved a generous recompense.

[57:20] Know that this worldly life is no more than play and games, and boasting among you, and hoarding of money and children. It is like abundant rain that produces plants and pleases the disbelievers. But then the plants turn into useless hay, and are blown away by the wind. In the Hereafter there is either severe retribution, or forgiveness from GOD and approval. This worldly life is no more than a temporary illusion.
