Tafsir

This verse: أَفَنَجْعَلُ الْمُسْلِمِينَ كَالْمُجْرِ‌مِينَ (Otherwise, shall We make the obedient like the sinners?... 68:35). Clarifies that it is rationally necessary that there should come a time when people will have to give account of their deeds, a place where the guilty ones will find no escape routes, an ideal world where there will be absolute justice and fair play, where good and evil will be clearly distinguished. If this is not the state of affairs in the Hereafter, then no evil should be evil, and no sin should be sin in this mortal world. Divine justice would thus be rendered meaningless.

Since it is established that Resurrection is a reality and inevitable, the reward of good deeds is a reality and the punishment of evil deeds is a reality, the verses that follow describe the horrors of the Day of Judgment and the punishment of the evil ones, including the description of the exposure of the Shin [ kashf-us-saq ] in Verse 42 (the explanation of which may be seen in the foot-note given in the translation of that verse.)
