فَكَذَّبُوْهُ فَاَخَذَهُمْ عَذَابُ يَوْمِ الظُّلَّةِ ۗاِنَّهٗ كَانَ عَذَابَ يَوْمٍ عَظِيْمٍ

Fa każżabūhu fa akhażahum ‘ażābu yaumiẓ-ẓullah(ti), innahū kāna ‘ażāba yaumin ‘aẓīm(in).

"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."
