وَأَنَّهُۥ كَانَ رِجَالٌۭ مِّنَ ٱلْإِنسِ يَعُوذُونَ بِرِجَالٍۢ مِّنَ ٱلْجِنِّ فَزَادُوهُمْ رَهَقًۭا
And there were men from mankind who sought refuge in men from the jinn, so they [only] increased them in burden.
وَأَنَّهُمْ ظَنُّوا۟ كَمَا ظَنَنتُمْ أَن لَّن يَبْعَثَ ٱللَّهُ أَحَدًۭا
And they had thought, as you thought, that Allah would never send anyone [as a messenger].
وَأَنَّا كُنَّا نَقْعُدُ مِنْهَا مَقَـٰعِدَ لِلسَّمْعِ ۖ فَمَن يَسْتَمِعِ ٱلْـَٔانَ يَجِدْ لَهُۥ شِهَابًۭا رَّصَدًۭا
And we used to sit therein in positions for hearing, but whoever listens now will find a burning flame lying in wait for him.
وَأَنَّا لَا نَدْرِىٓ أَشَرٌّ أُرِيدَ بِمَن فِى ٱلْأَرْضِ أَمْ أَرَادَ بِهِمْ رَبُّهُمْ رَشَدًۭا
And we do not know [therefore] whether evil is intended for those on earth or whether their Lord intends for them a right course.
