As-Saffaat - 37:177

فَإِذَا نَزَلَ بِسَاحَتِهِمْ فَسَاء صَبَاحُ الْمُنذَرِينَ
[37:177]
But when it shall descend in their court, evil shall then be the morning of the warned ones.
But when it descends into the open space before them, evil will be the morning for those who were warned (and heeded not)!
But when it cometh home to them, then it will be a hapless morn for those who have been warned.
