The Day that He assembles you (all) for a Day of Assembly,- that will be a Day of mutual loss and gain (among you), and those who believe in Allah and work righteousness,- He will remove from them their ills, and He will admit them to Gardens beneath which Rivers flow, to dwell therein for ever: that will be the Supreme Achievement.

Tafsir
People take the world to be a place of winning or losing (taghabun). One who is successful here becomes very happy, but one who meets with failure is looked upon with contempt. In this world, however, success is as valueless as failure is. The place of true success or failure is the Hereafter. One is a failure if he fails in the Hereafter and successful if he is successful in the Hereafter, and the criterion of success or failure there is entirely different from that of this world, where it is based on outward materialism: success or failure in the Hereafter will be on the basis of Divine moral values. At that time, people will be surprised to see that the whole complexion of things has completely changed. Gaining, which was considered as such will actually turn out to be losing, while what was considered as losing will turn out to be gaining in the real sense. Failure on that Day is real failure and success on that Day will be real success.
