Are there any authentic hadiths in Sahih al-Bukhari or Muslim that permit anal intercourse with a woman?

There is no hadith in Sahih al-Bukhari or Sahih Muslim regarding the prohibition of anal intercourse with a woman. However, the prohibition of this abominable act and its classification as a major sin is found in authentic hadiths outside of the Two Sahihs. Among these are the Prophet's (peace be upon him) sayings: "Whoever goes to a soothsayer and believes what he says, or has intercourse with a menstruating woman, or has anal intercourse with a woman, has disbelieved in what was revealed to Muhammad," and his saying: "Allah will not look at a man who has anal intercourse with his wife," and his saying: "Accursed is he who has anal intercourse with a woman." These hadiths confirm the prohibition of this act and that it is a major sin. It is not a condition for prohibition that a hadith be narrated in the Two Sahihs; rather, whenever a hadith is authentic, it must be acted upon, unless it is abrogated or contradicted.
