Genesis 19:24-29 ESV
Then the LORD rained on Sodom and Gomorrah sulfur and fire from the LORD out of heaven. And he overthrew those cities, and all the valley, and all the inhabitants of the cities, and what grew on the ground. But Lot’s wife, behind him, looked back, and she became a pillar of salt.
And Abraham went early in the morning to the place where he had stood before the LORD. And he looked down toward Sodom and Gomorrah and toward all the land of the valley, and he looked and, behold, the smoke of the land went up like the smoke of a furnace.
So it was that, when God destroyed the cities of the valley, God remembered Abraham and sent Lot out of the midst of the overthrow when he overthrew the cities in which Lot had lived.
