mockery of the Prophet

ٱنظُرْ كَيْفَ ضَرَبُوا۟ لَكَ ٱلْأَمْثَالَ فَضَلُّوا۟ فَلَا يَسْتَطِيعُونَ سَبِيلًا

Look how they strike for you comparisons; but they have strayed, so they cannot [find] a way.

أَوْ تُسْقِطَ ٱلسَّمَآءَ كَمَا زَعَمْتَ عَلَيْنَا كِسَفًا أَوْ تَأْتِىَ بِٱللَّهِ وَٱلْمَلَـٰٓئِكَةِ قَبِيلًا

Or you make the heaven fall upon us in fragments as you have claimed or you bring Allāh and the angels before [us]
