Quran 57:9 — Iron (Al-Hadeed)

He is the One who sends down to His servant clear revelations, in order to lead you out of the darkness into the light. GOD is Compassionate towards you, Most Merciful.

[57:8] Why should you not believe in GOD when the messenger is inviting you to believe in your Lord? He has taken a pledge from you, if you are believers.

[57:10] Why do you not spend in the cause of GOD, when GOD possesses all wealth in the heavens and the earth? Distinguished from the rest are those among you who spend before the victory and strive. They attain a greater rank than those who spend after the victory and strive. For each, GOD promises salvation. GOD is Cognizant of everything you do.
