"(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)

"So the Quraish and the Ansar became angry and said, "He (i.e. the Prophet, ) gives the chief of Najd and does not give us." The Prophet said, "I give them) so as to attract their hearts (to Islam)." - Sahih Bukhari 4:55:558 (read more)

"It is also incumbent upon Muslims that they should not accept from them [Jews] victuals with which they had come into contact, such as distillates, which cannot be purified. If something can be purified, such as clothes, if they are dry, they can be accepted, they are clean...It would also be better if the ruler of the Muslims would establish that all infidels could not move out of their homes on days when it rains or snows because they would make Muslims impure." - Muhammad Baqir Majlesi
