Indeed, they rejected the truth (The Quran and Muhammed) when it came to them, but there will come to them the news of that(the torment) which they used to mock at. Have they not seen how many generations before then We have destroyed whom We had established on the earth such as We have not established you? And We poured out on them rain from the sky in abundance, and made the rivers flow under them. Yet We destroyed them for their sins, and created after them other generations. Surah 6; 1-6.
