This Surah was revealed at Makkah at the time when opposition to the Prophet (pbuh) had started but had not yet become tyrannical.
- Description of the Day of Resurrection and the Day of Judgement.
- Righteous people and their reward.
- Sinful people and their punishment.
- Al-Qur'an is the word of Allah and not of the Prophet, and that it is a reminder for those who fear Allah (God).
The first section is about the Hereafter and the second about the Qur'an being a revelation from Allah and the Prophet being a true Rasool of Allah. The first section opens with the assertion that the coming of the Resurrection and the occurrence of the Hereafter is a truth which has to inevitably take place. The real object why Allah has destined a second life for mankind after the present worldly life is described depicting a scene from the Day of Judgement when all men shall appear in the court of their Rabb where no secret of theirs shall remain hidden and each man's record will be placed in his hand. Those who spent their lives in the world with the realization that one day they would have to render an account of their deeds before their Rabb, and who had worked righteously in the world and provided beforehand for their well being in the Hereafter, will rejoice when they see that they have been acquitted and blessed with the eternal bliss of paradise. On the contrary, those who neither recognized the rights of Allah, nor discharged the rights of men, will have no one to save them from the punishment of Allah, and they will be cast into hell.
In the second section the disbelievers of Makkah are addressed and told: "You think this Qur'an is the word of a poet or soothsayer, whereas it is a Revelation sent down by Allah, which is being presented by His noble Rasool. The Rasool by himself has no power to add or delete a word in it. If he forges something of his own composition into it, We will cut off his jugular vein."
