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,

﴿أَمْ حَسِبَ الَّذِينَ فِى قُلُوبِهِمْ مَّرَضٌ أَن لَّن يُخْرِجَ اللَّهُ أَضْغَـنَهُمْ ﴾

(Or do those in whose hearts is a disease (of hypocrisy), think that Allah will not bring to light all their hidden ill-wills) ﴿47:29﴾, until,

﴿وَلَتَعْرِفَنَّهُمْ فِى لَحْنِ الْقَوْلِ﴾

(but surely, you will know them by the tone of their speech!)﴿47:30﴾. This is why, according to Qatadah, this Surah is called `Al-Fadihah' (the Exposing), because it exposed the hypocrites.

﴿وَلَئِن سَأَلْتَهُمْ لَيَقُولُنَّ إِنَّمَا كُنَّا نَخُوضُ وَنَلْعَبُ قُلْ أَبِاللَّهِ وَءَايَـتِهِ وَرَسُولِهِ كُنتُمْ تَسْتَهْزِءُونَ - لاَ تَعْتَذِرُواْ قَدْ كَفَرْتُمْ بَعْدَ إِيمَـنِكُمْ إِن نَّعْفُ عَن طَآئِفَةٍ مِّنْكُمْ نُعَذِّبْ طَآئِفَةً بِأَنَّهُمْ كَانُواْ مُجْرِمِينَ ﴾

(65. If you ask them (about this), they declare: "We were only talking idly and joking.'' Say: "Was it at Allah, and His Ayat and His Messenger that you were mocking'') (66. Make no excuse; you disbelieved after you had believed. If We pardon some of you, We will punish others among you because they were criminals.)
