question #2 Sahih al-Bukhari 7166, Book 93, Hadith 30 : How does the concept of Lian function in resolving marital disputes in Islam?

(the brother of Bani Sa`ida) A man from the Ansar came to the Prophet (ﷺ) and said, “If a man finds
another man sleeping with his wife, should he kill him?” That man and his wife then did Lian in the
mosque while I was present.
