"(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)

"Narrated by Gaber bin Abdullah: We were with the messenger of Allah, PBUH and he asked for a drink. One of his men said: "Oh Messenger of Allah, Can we offer you wine to drink?" He said Yes. He (Gaber) went out looking for the drink and came back with a cup of wine. The messenger (PBUH) asked:”Have you fermented it, even with one piece of ferment?” He (Gaber) said "yes" and he (Muhammad) drank." - Sahih Muslim 3753 (read more)

"You should not initiate the greeting to a Jew or Christian. If a Muslim inadvertently greets a dhimmi, he does take it back. If a Jew or Christian greets a Muslim, he should answer, "On you ('alayk)." It is also said that one may answer with "And on you silam." "Silam" means a stone. That used to be said." - ibn Abi Zayd
