Is it permissible for a husband to have anal intercourse with his wife, citing the mentioned hadith from Omar ibn al-Khattab, the interpretation of the verse, "Your wives are a planting for you, so come to your planting however you wish," and comparing that to the story of Lot (peace be upon him)?

As for the story of Umar and the verse: "Your wives are a place of cultivation for you, so come to your place of cultivation however you wish," neither of them implies coming in the anus, but rather coming in the front from the rear. As for the saying of Lot (peace be upon him): "These are my daughters; they are purer for you," it does not contain proof for the permissibility of coming to women in their anuses. Rather, he directed his people to their women instead of men. Ibn Kathir mentioned in his tafsir (definition) that Lot directed them to what was more beneficial for them in this world and the Hereafter, and that the meaning of "my daughters" refers to the women of his nation, and a prophet is like a father to his nation.
