Ash-Shu'ara 26:189

فَكَذَّبُوهُ فَأَخَذَهُمْ عَذَابُ يَوْمِ ٱلظُّلَّةِ ۚ إِنَّهُۥ كَانَ عَذَابَ يَوْمٍ عَظِيمٍ

Fakadhabūhu fa-akhadhahum ʿadhābu yawmi l-ẓulati innahu kāna ʿadhāba yawmin ʿaẓīmin

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.
