Surah 27. An-Naml, Ayah 69

I.e., those who denied the reality of a life after death and, hence, of man's ultimate responsibility for his conscious doings. As pointed out in the preceding note, the unavoidable consequence of this denial is the loss of all sense of right and wrong: and this, in its turn. leads to spiritual and social chaos, and so to the downfall of communities and civilizations.

Even if the Unbelievers are unwilling to take any doctrine, they have only to observe what has actually happened on the earth, and they will see that evil always came to an evil end, and that Truth and righteousness ultimately won.
