Surah 54. Al-Qamar, Ayah 4

Lit., "in which there was a restraint": i.e., many an indication, in observable nature, of God's creative and re-creative power, as well as many a tiding, through God-inspired prophets, of a continuation of life after bodily death and, therefore, of the fact that a person's attitudes and doings in this world must have definite consequences in the life to come.

The stories of the sins of past generations having been visited with exemplary punishments were already in their possession, and should, if they had been wise, have opened their eyes and checked them in their mad career of sin. Five of these stories are again referred to later in this Sura by way of illustration.
