Quran 57:13 — Iron (Al-Hadeed)

On that day, the hypocrite men and women will say to those who believed, "Please allow us to absorb some of your light." It will be said, "Go back behind you, and seek light." A barrier will be set up between them, whose gate separates mercy on the inner side, from retribution on the outer side.

[57:12] The day will come when you see the believing men and women with their lights radiating ahead of them and to their right. Good news is yours that, on that day, you will have gardens with flowing streams. You will abide therein forever. This is the great triumph.

[57:14] They will call upon them, "Were we not with you?" They will answer, "Yes, but you cheated your souls, hesitated, doubted, and became misled by wishful thinking, until GOD's judgment came. You were diverted from GOD by illusions.
