Yameen al-Ghamous (Arabic: , literally the "submerging oath"), also known as the perjurious oath, refers to a false oath that an individual intentionally swears while knowing it is an absolute lie. It is termed ghamous (submerging) because it is thought to plunge the swearer into sin, or more literally, directly submerges them into the Hellfire.Imam Al-Dhahabi, Kitab al-Kaba'ir (The Book of Major Sins), p. 85.
