Surah 38. Sad, Ayah 28

By implication, belief in resurrection, judgment and life after death is postulated in this passage (verses {27-28}) as a logical corollary - almost a premise - of all belief in God: for, since we see that many righteous people suffer all manner of misery and deprivations in this world, while, on the other hand, many of the wicked and depraved enjoy their lives in peace and affluence, we must either assume that God does not exist (because the concept of injustice is incompatible with that of Godhead), or - alternatively - that there is a hereafter in which both the righteous and the unrighteous will harvest in full what they had morally sown during their lives on earth.

The reference to the Hereafter at the end of verse 26 above is of a piece with the whole tenor of this Sura, which deals with the superiority of the spiritual kingdom and the Hereafter. If there were no Hereafter, how could you reconcile the inequalities of this world? Would not the Unbelievers be right in acting as if all Creation and all life were futile? But there is a Hereafter and Allah will not treat the Good and Evil alike. He is just and will fully restore the balance disturbed in this life.
