Surah 83. Al-Mutaffifin, Ayah 32

The wicked laugh at the righteous in this world in many ways: (1) They inwardly laugh at their Faith, because they feel themselves so superior. (2) In public places, when the righteous pass, they wink at each other and insult them. (3) In their own houses they run them down. (4) Whenever and wherever they see them, they reproach them with being fools who have lost their way, when the boot is really on the other leg. In the Hereafter all these tricks and falsehoods will be shown for what they are, and the tables will be reversed.
