The Prostration
وَأَمَّا ٱلَّذِينَ فَسَقُوا۟ فَمَأْوَىٰهُمُ ٱلنَّارُ ۖ كُلَّمَآ أَرَادُوٓا۟ أَن يَخْرُجُوا۟ مِنْهَآ أُعِيدُوا۟ فِيهَا وَقِيلَ لَهُمْ ذُوقُوا۟ عَذَابَ ٱلنَّارِ ٱلَّذِى كُنتُم بِهِۦ تُكَذِّبُونَ
But as for those who defiantly disobeyed, their refuge is the Fire. Every time they wish to emerge from it, they will be returned to it while it is said to them, "Taste the punishment of the Fire which you used to deny."
Nearby ayahs help place verse 32:20 in sequence and meaning.
أَفَمَن كَانَ مُؤْمِنًا كَمَن كَانَ فَاسِقًا ۚ لَّا يَسْتَوُۥنَ
Then is one who was a believer like one who was defiantly disobedient? They are not equal.
أَمَّا ٱلَّذِينَ ءَامَنُوا۟ وَعَمِلُوا۟ ٱلصَّـٰلِحَـٰتِ فَلَهُمْ جَنَّـٰتُ ٱلْمَأْوَىٰ نُزُلًۢا بِمَا كَانُوا۟ يَعْمَلُونَ
As for those who believed and did righteous deeds, for them will be the Gardens of Refuge as accommodation for what they used to do.
وَلَنُذِيقَنَّهُم مِّنَ ٱلْعَذَابِ ٱلْأَدْنَىٰ دُونَ ٱلْعَذَابِ ٱلْأَكْبَرِ لَعَلَّهُمْ يَرْجِعُونَ
And we will surely let them taste the nearer punishment short of the greater punishment that perhaps they will repent.
وَمَنْ أَظْلَمُ مِمَّن ذُكِّرَ بِـَٔايَـٰتِ رَبِّهِۦ ثُمَّ أَعْرَضَ عَنْهَآ ۚ إِنَّا مِنَ ٱلْمُجْرِمِينَ مُنتَقِمُونَ
And who is more unjust than one who is reminded of the verses of his Lord; then he turns away from them? Indeed We, from the criminals, will take retribution.
