Surah 72. Al-Jinn, Ayah 15

With this assertion ends, according to all classical commentators, the "confession of faith" of the beings described at the beginning of this passage as jinn. Whatever be the real meaning of this term in the present instance - whether it signifies "unseen beings" of a nature unknown to man or, alternatively, a group of humans from distant lands - matters little, for the context makes it abundantly clear that the "speech" of those beings is but a parable of the guidance which the Qur'an offers to a mind intent on attaining to "consciousness of what is right".

An unjust life carries its own condemnation. It does no good to itself or to any one else. It bears no fruit. It becomes merely fuel for the Fire of Punishment.
