Punishment of the grave

وَمِمَّنْ حَوْلَكُم مِّنَ ٱلْأَعْرَابِ مُنَٰفِقُونَ ۖ وَمِنْ أَهْلِ ٱلْمَدِينَةِ ۖ مَرَدُوا۟ عَلَى ٱلنِّفَاقِ لَا تَعْلَمُهُمْ ۖ نَحْنُ نَعْلَمُهُمْ ۚ سَنُعَذِّبُهُم مَّرَّتَيْنِ ثُمَّ يُرَدُّونَ إِلَىٰ عَذَابٍ عَظِيمٍۢ

Certain of the desert Arabs round about you are hypocrites, as well as (desert Arabs) among the Medina folk: they are obstinate in hypocrisy: thou knowest them not: We know them: twice shall We punish them: and in addition shall they be sent to a grievous penalty.

ٱلنَّارُ يُعْرَضُونَ عَلَيْهَا غُدُوًّۭا وَعَشِيًّۭا ۖ وَيَوْمَ تَقُومُ ٱلسَّاعَةُ أَدْخِلُوٓا۟ ءَالَ فِرْعَوْنَ أَشَدَّ ٱلْعَذَابِ

In front of the Fire will they be brought, morning and evening: And (the sentence will be) on the Day that Judgment will be established: "Cast ye the People of Pharaoh into the severest Penalty!"

كَلَّا سَوْفَ تَعْلَمُونَ

But nay, ye soon shall know (the reality).
