وَأَمْطَرْنَا عَلَيْهِم مَّطَرًا فَسَاء مَطَرُ الْمُنذَرِينَ
[27:58]
And We rained on them a rain, and evil was the rain of those who had been warned.
And 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 a rain upon them. Dreadful is the rain of those who have been warned.
