Abu Yahya Suhaib b. Sinan narrated that the Messenger of Allah صلى الله عليه وسلم said: “Wondrous are the believer’s affairs. For him there is good in all his affairs, and this is so only for the believer. When something pleasing happens to him, he is grateful, and that is good for him; and when something displeasing happens to him, he is enduring (sabar), and that is good for him. “
