Prophet Hud - 11:81
"(The angels) said: "O Lot,"they said, "We are the messengers of your Lord. They cannot touch you. Take your family for a walk at night, and let none of you look back, except your wife. What will befall the others will befall her. Their appointed time is the morning. Is the morning not near?"
Why was Lot's wife among those destroyed?
The Prohibition/66:10
"Allah gives the example of Noah´s wife and Lot´s wife to the disbelievers. They were under the marriage of two righteous servants, but they betrayed them. Their husbands could not ward off anything from Allah. They were both told, "Enter Hell with those who enter it."
