9:64
يَحْذَرُ ٱلْمُنَٰفِقُونَ أَن تُنَزَّلَ عَلَيْهِمْ سُورَةٌۭ تُنَبِّئُهُم بِمَا فِى قُلُوبِهِمْ ۚ قُلِ ٱسْتَهْزِءُوٓا۟ إِنَّ ٱللَّهَ مُخْرِجٌۭ مَّا تَحْذَرُونَ
They hypocrites are apprehensive lest a surah be revealed about them, informing them of what is in their hearts. Say, "Mock [as you wish]; indeed, Allah will expose that which you fear."

Tafsir
Ibn Kathīr (abridged)
The Hypocrites fear Public Exposure of Their Secrets
Mujahid said, "The hypocrites would say something to each other then declare, `We wish that Allah does not expose this secret of ours," There is a similar Ayah to this one, that is, Allah's statement,
وَإِذَا جَآءُوكَ حَيَّوْكَ بِمَا لَمْ يُحَيِّكَ بِهِ اللَّهُ وَيَقُولُونَ فِى أَنفُسِهِمْ لَوْلاَ يُعَذِّبُنَا اللَّهُ بِمَا نَقُولُ حَسْبُهُمْ جَهَنَّمُ يَصْلَوْنَهَا فَبِئْسَ الْمَصِيرُ
(And when they come to you, they greet you with a greeting wherewith Allah greets you not, and say within themselves: "Why should Allah punish us not for what we say" Hell will be sufficient for them; they will burn therein. And worst indeed is that destination!) 58:8. Allah said in this Ayah,
قُلِ اسْتَهْزِءُواْ إِنَّ اللَّهَ مُخْرِجٌ مَّا تَحْذَرُونَ
(Say: "(Go ahead and) mock! But certainly Allah will bring to light all that you fear."), He will expose and explain your reality to His Messenger through revelation. Allah said in other Ayat,
