Surah Ash-Shu'ara 26:189

فَكَذَّبُوهُ فَأَخَذَهُمْ عَذَابُ يَوْمِ ٱلظُّلَّةِ ۚ إِنَّهُۥ 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.

Translation: Saheeh International

Tafsir

But they denied him so they were seized by the chastisement of the day of the shade al-zulla — a cloud which gave them shade when they suffered a bout of extreme heat but which then rained down fire on them and they were incinerated. Assuredly it was the chastisement of a tremendous day.
