"Permitted to you, on the night of the fasts, is the approach to your wives. They are your garments and ye are their garments. Allah knoweth what ye used to do secretly among yourselves; but He turned to you and forgave you; so now associate with them, and seek what Allah Hath ordained for you, and eat and drink, until the white thread of dawn appear to you distinct from its black thread; then complete your fast Till the night appears; but do not associate with your wives while ye are in retreat in the mosques. Those are Limits (set by) Allah: Approach not nigh thereto. Thus doth Allah make clear His Signs to men: that they may learn self-restraint." - Quran 2:187 (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
