You already know this, don't you. You will find this story in the First Book of Moses, ch. 19. WHO was Lot? He was Abraham's (the Moslems's forefather too!)brother's Haaran's son. Haaran himself died before his and Abraham's father Terah. (Moses I, 11:27-32). Lot with his wife and company moved to a city called Sodoma, who was so sinful that its sins became intolerable before G-D's eyes and therefore He decided to destroy it. Lot was the only righteous person in the city and G-D wanted to spare Lot's family and exhorted them to leave the city. G-D told them NOT to look behind, when He destroys the city, but Lot's wife was curious and did not obey, but looked and turned into a salt-statue....still there(!) Atilla, these events(Moslems call fairy-tales, so why believe this one?) took place at dawn of mankind's history: the moral-codes and the ethics have come about as we've proceeded in time and evolved. In verse 31 you find the reason to Lot's daughters incestous act.
