To be content with a thing doesn’t mean that you are personally happy with it. It means that: I am content with God, my Lord, who has ordained this for me. We can be content in happiness, and content in sadness. All the things that transpire in our lives are from God. He willed for it to be. Contentment is a type of submission: I have no complaints against Him, and I can do the best in the situation that I am in, and I will seek to find the wisdom that God has in this.
— Shaykh Dr. Umar Faruq Abd-Allah
