أَوْ تُسْقِطَ ٱلسَّمَآءَ كَمَا زَعَمْتَ عَلَيْنَا كِسَفًا أَوْ تَأْتِىَ بِٱللَّهِ وَٱلْمَلَٰٓئِكَةِ قَبِيلًا
Commentary:
Disbelievers mockingly told the Holy Prophet, that, if he could not bring to them any of the good things which they demanded he might as well cause the sky to fall upon them or let God and His angels destroy them.
