Qur'ān 9:64 · At-Tawbah (التوبة)

يَحْذَرُ ٱلْمُنَـٰفِقُونَ 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."
