Then, when the Messengers (the angels) came unto the family of Lot, he said: "Verily! You are people unknown to me." They said: "Nay, we have come to you with that (torment) which they have been doubting. And we have brought to you the truth (the news of the destruction of your nation) and certainly, we tell the truth. Then travel in apart of the night with your family, and you go behind them in the rear, and let no one amongst you look back, but go on to where you are ordered."

And We made known this decree to him, that the root of those (sinners) was to be cut off in the early morning.

And the inhabitants of the city came rejoicing (at the news of the young men's arrival). (Lot) said: "Verily! These are my guests, so shame me not. And fear Allah and disgrace me not." They (people of the city) said: 'Did we not forbid you to entertain (or protect) any of the 'Alamin (people, foreigners, strangers, etc.) from us?" (Lot) said: "These (the girls of the nation) are my daughters (to marry lawfully), if you must act (so)."

Verily, by your life (0 Muhammad), in their wild intoxication they were wandering blindly. So As-Saiha (torment - awful cry, etc.) overtook them at the time of sunrise; and We turned (the towns of Sodom in Palestine) upside down and rained down on them stones of baked clay. Surely! In this are signs for those who see (or understand or learn the lessons from the Signs of Allah). And verily! They (the cities) are right on the highroad (from Mecca to Syria, i.e. the place where the Dead Sea is now). Surely! Therein is indeed a sign for the believers. Surah 15: 51-77

Allah the Exalted also declared: So We saved him and his family, all, - except an old woman (his wife) among those who remained behind. Then afterward We destroyed the others. And We rained on them a rain (of torment). And how evil was the rain of those who had been warned. Verily, in this is indeed a sign, yet most of them are not believers. And verily! Your Lord, He is indeed the All-Mighty, the Most Merciful. Surah 26: 170-175

Lot's Life After Sodom
The book was closed on the people of Lot . Their towns and names have been erased from the face of the earth. Gone are they from memory. One book was closed of the books of corruption.
Lot proceeded towards Abraham . He visited him, and when he recounted the story of his people, he was surprised to learn that Abraham already knew. And so Lot continued to invite people to Allah, as did Abraham , the patient one who turned to Allah repentantly, and the two held firm to their mission.
