Surah 78. An-Naba, Ayah 21

Hell, the embodiment of evil, is lying in wait like an ambush for every one. We should be on our guard. For the transgressors, those who have wilfully rebelled against Allah, it will be a definite destination, from which there is no return, except, it may be, after ages, i.e., unless Allah so wills: Cf. vi. 128, and n. 951.
