(44) CHAPTER. To give the judicial verdicts in the mosque and to perform the Al-Lian between men and women (husbands and wives) there.
Narrated Sahl bin Sa`d: A man said, O Allah's Apostle! If a man finds another man with his wife, (committing adultery) should the husband kill him? Later on I saw them (the man and his wife) doing Li`an in the mosque (taking oaths, one accusing, and the other denying adultery).
