وَأَمْطَرْنَا عَلَيْهِم مَّطَرًا فَسَاء مَطَرُ الْمُنذَرِينَ
[26:173]
And We rained down upon them a rain, and evil was the rain on those warned.
We rained down on them a shower (of brimstone): and evil was the shower on those who were admonished (but heeded not)!
And We rained on them a rain. And dreadful is the rain of those who have been warned.
