Surah 76. Al-Insan, Ayah 27

Fleeting life: Cf. lxxv. 20. They: the immediate reference was to the Pagan Quraish: the general reference is to the Unbelievers of all ages. They reject, or at least put away the thought of, a Hereafter, a Day that will be hard, for the easy pleasures of a fleeting life.
