Genesis 19:24-29

Then the Lord rained down fire and burning sulfur from the sky on Sodom and Gomorrah. He completely destroyed the towns and all their inhabitants, the whole valley and everything growing there. But Lot's wife, who was lagging behind, looked back, and she turned into a pillar of salt. Abraham got up early the next morning and went back to where he had stood before the Lord. He looked down at Sodom and Gomorrah and the whole valley floor, and saw the land burning, sending up smoke like from a furnace. When God destroyed the towns of the valley he didn't forget the promise he made Abraham, and he saved Lot from the destruction of the towns where Lot was living.
