Ali 'Imran · 3:140

140. O believers, if you suffered injuries and losses on the day of Uḥud, then the disbelievers also suffered injuries and losses just as you did. Allah distributes such days between people, whether they have faith or disbelieve, giving victory and defeat as He wills, for reasons of great wisdom. Among these reasons is to make it clear, those who truly have faith as opposed to those who are hypocrites, and to honour whomever He wills with martyrdom in His cause. Allah dislikes those who wrong themselves by giving up striving in his path.
