Shirk (polytheism) and its consequences

سَنُلْقِى فِى قُلُوبِ ٱلَّذِينَ كَفَرُوا۟ ٱلرُّعْبَ بِمَآ أَشْرَكُوا۟ بِٱللَّهِ مَا لَمْ يُنَزِّلْ بِهِۦ سُلْطَـٰنًا ۖ وَمَأْوَىٰهُمُ ٱلنَّارُ ۚ وَبِئْسَ مَثْوَى ٱلظَّـٰلِمِينَ

We will cast terror into the hearts of those who disbelieve for what they have associated with Allāh of which He had not sent down [any] authority. And their refuge will be the Fire, and wretched is the residence of the wrongdoers.

ثُمَّ يَوْمَ ٱلْقِيَـٰمَةِ يُخْزِيهِمْ وَيَقُولُ أَيْنَ شُرَكَآءِىَ ٱلَّذِينَ كُنتُمْ تُشَـٰٓقُّونَ فِيهِمْ ۚ قَالَ ٱلَّذِينَ أُوتُوا۟ ٱلْعِلْمَ إِنَّ ٱلْخِزْىَ ٱلْيَوْمَ وَٱلسُّوٓءَ عَلَى ٱلْكَـٰفِرِينَ

Then on the Day of Resurrection He will disgrace them and say, "Where are My 'partners' for whom you used to oppose [the believers]?" Those who were given knowledge will say, "Indeed disgrace, this Day, and evil are upon the disbelievers" -

وَيَوْمَ يَحْشُرُهُمْ وَمَا يَعْبُدُونَ مِن دُونِ ٱللَّهِ فَيَقُولُ ءَأَنتُمْ أَضْلَلْتُمْ عِبَادِى هَـٰٓؤُلَآءِ أَمْ هُمْ ضَلُّوا۟ ٱلسَّبِيلَ

And [mention] the Day He will gather them and that which they worship besides Allāh and will say, "Did you mislead these, My servants, or did they [themselves] stray from the way?"

إِذْ نُسَوِّيكُم بِرَبِّ ٱلْعَـٰلَمِينَ

When we equated you with the Lord of the worlds.

لِيَكْفُرُوا۟ بِمَآ ءَاتَيْنَـٰهُمْ ۚ فَتَمَتَّعُوا۟ فَسَوْفَ تَعْلَمُونَ

So that they will deny what We have granted them. Then enjoy yourselves, for you are going to know.

لَهُم مِّن فَوْقِهِمْ ظُلَلٌ مِّنَ ٱلنَّارِ وَمِن تَحْتِهِمْ ظُلَلٌ ۚ ذَٰلِكَ يُخَوِّفُ ٱللَّهُ بِهِۦ عِبَادَهُۥ ۚ يَـٰعِبَادِ فَٱتَّقُونِ

They will have canopies [i.e., layers] of fire above them and below them, canopies. By that Allāh threatens [i.e., warns] His servants. O My servants, then fear Me.
