certainty of Allah's judgment

يَحْذَرُ ٱلْمُنَـٰفِقُونَ أَن تُنَزَّلَ عَلَيْهِمْ سُورَةٌ تُنَبِّئُهُم بِمَا فِى قُلُوبِهِمْ ۚ قُلِ ٱسْتَهْزِءُوٓا۟ إِنَّ ٱللَّهَ مُخْرِجٌ مَّا تَحْذَرُونَ

The hypocrites are apprehensive lest a sūrah be revealed about them, informing them of what is in their hearts. Say, "Mock [as you wish]; indeed, Allāh will expose that which you fear."

ثُمَّ لَنَحْنُ أَعْلَمُ بِٱلَّذِينَ هُمْ أَوْلَىٰ بِهَا صِلِيًّا

Then, surely it is We who are most knowing of those most worthy of burning therein.

فَٱرْتَقِبْ إِنَّهُم مُّرْتَقِبُونَ

So watch, [O Muḥammad]; indeed, they are watching [for your end].
