This Surah takes its name from v. 80.
It is clear from its topics and style that the period of its revelation is about the same as that of Surah Ibrahim, for two things are quite prominent in its background. First, it appears from the repeated warnings in this Surah that in spite of the fact that the Holy Prophet had been propagating the Message for many years, his people in general had not shown any inclination towards its acceptance nay, they had become more and more obdurate and stubborn in their antagonism, enmity and ridicule with the passage of time. Secondly, by that time the Holy Prophet had begun to feel a little tired of making strenuous efforts to eradicate disbelief and opposition of his people. That is why Allah has consoled and comforted him over and over again by way of encouragement.
Though the main topics of the surah are:
warning to those who rejected his Message, opposed it tooth and nail, and ridiculed him, and
comfort and encouragement to the Holy Prophet,
It does not mean that this Surah does not contain admonition and instructions. As a matter of fact, the Quran never confines itself to mere warning; rebuke and censure, but resorts to precept in every suitable place. Accordingly, this Surah contains brief arguments for Tauhid on the one hand, and admonition in the story of Adam and Satan on the other.

وَإِن مِّن شَيْءٍ إِلَّا عِندَنَا خَزَائِنُهُ وَمَا نُنَزِّلُهُ إِلَّا بِقَدَرٍ مَّعْلُومٍ
وَأَرْسَلْنَا الرِّيَاحَ لَوَاقِحَ فَأَنزَلْنَا مِنَ السَّمَاءِ مَاءً فَأَسْقَيْنَاكُمُوهُ وَمَا أَنتُمْ لَهُ بِخَازِنِينَ
وَإِنَّا لَنَحْنُ نُحْيِي وَنُمِيتُ وَنَحْنُ الْوَارِثُونَ
وَلَقَدْ عَلِمْنَا الْمُسْتَقْدِمِينَ مِنكُمْ وَلَقَدْ عَلِمْنَا الْمُسْتَأْخِرِينَ
وَإِنَّ رَبَّكَ هُوَ يَحْشُرُهُمْ ۚ إِنَّهُ حَكِيمٌ عَلِيمٌ
وَلَقَدْ خَلَقْنَا الْإِنسَانَ مِن صَلْصَالٍ مِّنْ حَمَإٍ مَّسْنُونٍ
وَالْجَانَّ خَلَقْنَاهُ مِن قَبْلُ مِن نَّارِ السَّمُومِ
وَإِذْ قَالَ رَبُّكَ لِلْمَلَائِكَةِ إِنِّي خَالِقٌ بَشَرًا مِّن صَلْصَالٍ مِّنْ حَمَإٍ مَّسْنُونٍ
فَإِذَا سَوَّيْتُهُ وَنَفَخْتُ فِيهِ مِن رُّوحِي فَقَعُوا لَهُ سَاجِدِينَ
