Ash-Shu'ara 26:188

قَالُوا إِنَّمَا أَنتَ مِنَ الْمُسَحَّرِينَ

They said, "You are only of those affected by magic.

وَمَا أَنتَ إِلَّا بَشَرٌ مِّثْلُنَا وَإِن نَّظُنُّكَ لَمِنَ الْكَاذِبِينَ

You are but a man like ourselves, and indeed, we think you are among the liars.

فَأَسْقِطْ عَلَيْنَا كِسَفًا مِّنَ السَّمَاءِ إِن كُنتَ مِنَ الصَّادِقِينَ

So cause to fall upon us fragments of the sky, if you should be of the truthful."

فَكَذَّبُوهُ فَأَخَذَهُمْ عَذَابُ يَوْمِ الظُّلَّةِ ۚ إِنَّهُ كَانَ عَذَابَ يَوْمٍ عَظِيمٍ

And they denied him, so the punishment of the day of the black cloud seized them. Indeed, it was the punishment of a terrible day.

إِنَّ فِي ذَٰلِكَ لَآيَةً ۖ وَمَا كَانَ أَكْثَرُهُم مُّؤْمِنِينَ

Indeed in that is a sign, but most of them were not to be believers.

وَإِنَّ رَبَّكَ لَهُوَ الْعَزِيزُ الرَّحِيمُ

And indeed, your Lord - He is the Exalted in Might, the Merciful.
