Surah 86. At-Tariq, Ayah 13

Lit., "a decisive word", or "word of distinction", i.e., between the true and the false - in this case, belief in a continuation of life after "death", on the one hand, and a denial of its possibility, on the other. (Cf. 37:21 , 44:40 , 77:13 and {38}, and 78:17 , where Resurrection Day is spoken of as "the Day of Distinction"; see also note [6] on 77:13 .)

See the last two notes. Revelation-Allah's Truth-can pierce through the hardest crusts, and ever lead us back to the centre and goal of our life: for it separates Good from Evil definitely. It is not mere play or amusement, any more than the Sky or the Earth is. It helps us in the highest issues of our life.
