Suhaib (may Allah be pleased with him) reports that the Messenger of Allah (peace and blessings be upon him) said: "The affair of the believer is indeed amazing; all of his affairs are good for him, and this is only for the believer. If something good happens to him, he is grateful, and that is better for him. If something harmful befalls him, he is patient, and that is better for him." Narrated by Muslim.
