Hud · 11:81

81. The angels said to Lot (peace be upon him) that they were messengers sent by Allah, and that his people would not be able to touch him with their evil. They told him to leave the town at night, when it was dark, with his family. They said that no one should turn to look at what was behind them, except for his wife, who would turn back wrongly, because the punishment that would come upon his people would also come upon her. They told Lot that the appointed time for their destruction would be the morning, and that it was nearly time.
