We run after the materialistic things of the world and end up depressed, frustrated and hopeless. That is bound to happen because this life is temporary and a test and nothing will ever be perfect.
Work hard to improve yourself and the world around you with the intention of seeking Allah’s pleasure and you will not be disappointed, hurt, depressed or hopeless.
Don’t expect from creation because it is weak and dependent. Expect from the Creator, the All-Mighty and He will be sufficient for you.
