Surah 20. Ta-Ha, Ayah 101

Cf. vi. 31. If people are so immersed in the evanescent falsehoods of this life as to turn away from the True and the Eternal, they will have a rude awakening when the Judgment comes. These very things that they thought so enjoyable here-taking advantage of others, material self-indulgence, nursing grievances instead of doing good, etc., etc.,-will be a grievous burden to them that day, which they will not be able to escape or lighten.
