"(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 Qatada: Anas bin Malik said, "The Prophet used to visit all his wives in a round, during the day and night and they were eleven in number." I asked Anas, "Had the Prophet the strength for it?" Anas replied, "We used to say that the Prophet was given the strength of thirty (men)." And Sa'id said on the authority of Qatada that Anas had told him about nine wives only (not eleven)." - Sahih Bukhari 1:5:268 (read more)

"It is proven by the scholars who studied the Prophet’s biography in detail that he ate mutton that had been poisoned by a Jewish woman in Khaybar, ... When his final illness came, he (peace and blessings of Allaah be upon him) said: “O ‘Aa’ishah, I still feel the pain of the food that I ate in Khaybar, and this time I feel that my aorta is being cut from that poison.” Narrated by al-Bukhaari in his Saheeh. So there is no room for doubt that this poison affected his body, since it is proven in al-Saheeh and elsewhere." - Islam Q&A
