This Surah, like many other Meccan Suras, contains short, meaningful, awakening verses with abundant warnings.
There are several oaths mentioned in the first part of the Surah that have no precedent and are primarily for warning the transgressors about the divine punishment.
Another part of this Surah points to some of the ancient rebellious nations, such as the 'Ad and Thamood people; and also to Pharaoh. The transgressor, and the divine punishment that destroyed them, which is a lesson for all arrogant powers so that they may take careful account of their situation.
In the next part of the Surah, which relates to the previous parts, Man's trial is mentioned and his neglect, in doing good deeds, is very sharply criticized.
In the last part of the Surah the discussion is about the Hereafter and the fate of the sinners and unbelievers, and presents a contrast in regard to the great rewards that the believers will receive; those whose souls are at rest.
