Abraham
مَّثَلُ ٱلَّذِينَ كَفَرُوا۟ بِرَبِّهِمْ ۖ أَعْمَـٰلُهُمْ كَرَمَادٍ ٱشْتَدَّتْ بِهِ ٱلرِّيحُ فِى يَوْمٍ عَاصِفٍ ۖ لَّا يَقْدِرُونَ مِمَّا كَسَبُوا۟ عَلَىٰ شَىْءٍ ۚ ذَٰلِكَ هُوَ ٱلضَّلَـٰلُ ٱلْبَعِيدُ
The example of those who disbelieve in their Lord is [that] their deeds are like ashes which the wind blows forcefully on a stormy day; they are unable [to keep] from what they earned a [single] thing. That is what is extreme error.

مِّن وَرَآئِهِۦ جَهَنَّمُ وَيُسْقَىٰ مِن مَّآءٍ صَدِيدٍ
Before him is Hell, and he will be given a drink of purulent water.
يَتَجَرَّعُهُۥ وَلَا يَكَادُ يُسِيغُهُۥ وَيَأْتِيهِ ٱلْمَوْتُ مِن كُلِّ مَكَانٍ وَمَا هُوَ بِمَيِّتٍ ۖ وَمِن وَرَآئِهِۦ عَذَابٌ غَلِيظٌ
He will gulp it but will hardly [be able to] swallow it. And death will come to him from everywhere, but he is not to die. And before him is a massive punishment.
أَلَمْ تَرَ أَنَّ ٱللَّهَ خَلَقَ ٱلسَّمَـٰوَٰتِ وَٱلْأَرْضَ بِٱلْحَقِّ ۚ إِن يَشَأْ يُذْهِبْكُمْ وَيَأْتِ بِخَلْقٍ جَدِيدٍ
Have you not seen that Allah created the heavens and the earth in truth? If He wills, He can do away with you and produce a new creation.
وَمَا ذَٰلِكَ عَلَى ٱللَّهِ بِعَزِيزٍ
And that is not difficult for Allah.
