"(We also sent) Lut (as a messenger): behold, He said to his people, "Do ye do what is shameful though ye see (its iniquity)? Would ye really approach men in your lusts rather than women? Nay, ye are a people (grossly) ignorant! But his people gave no other answer but this: they said, "Drive out the followers of Lut from your city: these are indeed men who want to be clean and pure!" Then We saved him and his household save his wife; We destined her to be of those who stayed behind. And We rained down on them a shower (of brimstone): and evil was the shower on those who were admonished (but heeded not)! - Quran 27:54 (read more)
