The chapter begins (verses 1 to 5) by mentioning events that will happen on the Day of Judgment, including the sundering of the sky and the flattening of all that is on earth. Verses 6 to 15 talk about the disparity between those who in that day will be "given [their] book in [their] right hand" and have a joyful reckoning, and those who will not. A series of oaths (verses 16—18) followed, and then another contrast between the fate of the believers and the unbelievers in the day of judgment.
