The Spider
يَوْمَ يَغْشَىٰهُمُ ٱلْعَذَابُ مِن فَوْقِهِمْ وَمِن تَحْتِ أَرْجُلِهِمْ وَيَقُولُ ذُوقُوا۟ مَا كُنتُمْ تَعْمَلُونَ
On the Day the punishment will cover them from above them and from below their feet and it is said, "Taste [the result of] what you used to do."

وَيَسْتَعْجِلُونَكَ بِٱلْعَذَابِ ۚ وَلَوْلَآ أَجَلٌ مُّسَمًّى لَّجَآءَهُمُ ٱلْعَذَابُ وَلَيَأْتِيَنَّهُم بَغْتَةً وَهُمْ لَا يَشْعُرُونَ
And they urge you to hasten the punishment. And if not for [the decree of] a specified term, punishment would have reached them. But it will surely come to them suddenly while they perceive not.
يَسْتَعْجِلُونَكَ بِٱلْعَذَابِ وَإِنَّ جَهَنَّمَ لَمُحِيطَةٌۢ بِٱلْكَـٰفِرِينَ
They urge you to hasten the punishment. And indeed, Hell will be encompassing of the disbelievers
يَـٰعِبَادِىَ ٱلَّذِينَ ءَامَنُوٓا۟ إِنَّ أَرْضِى وَٰسِعَةٌ فَإِيَّـٰىَ فَٱعْبُدُونِ
O My servants who have believed, indeed My earth is spacious, so worship only Me.
كُلُّ نَفْسٍ ذَآئِقَةُ ٱلْمَوْتِ ۖ ثُمَّ إِلَيْنَا تُرْجَعُونَ
Every soul will taste death. Then to Us will you be returned.
