Surah 51. Az-Zariyat, Ayah 8

Lit., "you are indeed in a discordant opinion (qawl)", i.e., as to whether or not there is life after death, whether God exists, whether there is any truth in divine revelation, and so forth.

 See footnote for 50:5.

Qaul=saying, word, theory, doctrine. Mukhtalif =differing, various, inconsistent with itself, discordant. No theory or doctrine based on a denial of a Hereafter can be consistent with spiritual facts as we know them, or with Allah's Goodness, Justice, and Mercy.
