Quran 57:6 — Iron (Al-Hadeed)

He merges the night into the day, and merges the day into the night. He is fully aware of the innermost thoughts.

[57:5] To Him belongs the kingship of the heavens and the earth. All matters are controlled by GOD.

[57:7] Believe in GOD and His messenger, and give from what He has bestowed upon you. Those among you who believe and give (to charity) have deserved a great recompense.
