The Hadith series is based on Bill Warner’s book The Political Traditions of Mohammed – The Hadith for Unbelievers. It is a compilation of all the Hadith (Traditions) related to non-Muslims. The Political Traditions of Mohammed contains both sets of Islamic ethics – one for the Muslim and one for the unbelievers.
Chapter 1 Ethics
Treatment Of Fellow Muslims (4)
A Muslim can swear a false oath by any other god and not be accountable.
B8,73,73 Mohammed: “A Muslim who swears a false oath by the god of
another religion is not obligated to fulfill that promise because he cannot
be bound by a faith he does not hold.”
