"Warnings are of 3 kinds and stages in the Quran:
1) Destruction of a nation (i.e. Nation of Prophets Nuh & Lut)
2) Warning of Judgment Day
3) Warning of Hellfire
All 3 kinds of warnings are related. Allah is telling us that if we are one of the nations that will be destroyed here, then we are really going to take a beating on Judgment Day, and that will feel like a vacation compared to Hellfire."
