The central theme of the chapter is the day of judgement and the three classes of people:
The amazing companions of the right.
The unfortunate companions of the left.
The awesome successful winners.
The chapter describes the rewards in Janna for the awesome winners and the righteous companions of the right in contrast to the punishment of the unfortunate companions of the left who were wasteful and denied Divinity and resurrection. The nature of the revelation of the Qur’an as honourable guidance follows.
The chapter ends with the nature of death and the afterlife, concluding with an order to declare the perfection of Allah.
