Genesis 19:24-29

Then the Lord rained on Sodom and on Gomorrah brimstone and fire from the Lord out of the heavens. He overthrew, destroyed, and ended those cities, and all the valley and all the inhabitants of the cities, and what grew on the ground. But [Lot's] wife looked back from behind him, and she became a pillar of salt. Abraham went up early the next morning to the place where he [only the day before] had stood before the Lord. And he looked toward Sodom and Gomorrah, and toward all the land of the valley, and saw, and behold, the smoke of the country went up like the smoke of a furnace. When God ravaged and destroyed the cities of the plain [of Siddim], He [earnestly] remembered Abraham [imprinted and fixed him indelibly on His mind], and He sent Lot out of the midst of the overthrow when He overthrew the cities where Lot lived.
