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."
The Saheeh International Quran Translation
يَحْذَرُ ٱلْمُنَٰفِقُونَ أَن تُنَزَّلَ عَلَيْهِمْ سُورَةٌ تُنَبِّئُهُم بِمَا فِى قُلُوبِهِمْ قُلِ ٱسْتَهْزِءُوٓا۟ إِنَّ ٱللَّهَ مُخْرِجٌ مَّا تَحْذَرُونَThey 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."
