Surah Al-Kahf Verse 7

2332 This world's goods-worldly power, glory, wealth, position, and all that men scramble for-are but a fleeting show. The possession or want of them does not betoken a man's real value or position in the spiritual world, the world which is to endure. Yet they have their uses. They test a man's sterling quality. He who becomes their slave loses rank in the spiritual world. He who uses them if he gets them, and does not fall into despair if he does not get them, shows his true mettle and quality. His conduct proclaims him.
