Is it permissible for a Muslim man to marry a Unitarian woman who believes in one God, but does not yet believe in the prophets, by analogy with the permissibility of his marriage to a woman of the People of the Book who believes in some prophets but not others?

Belief in Allah includes the belief in His oneness and worshipping Him, and belief in His Books and His Messengers. The believer must respond to Allah's command and hasten to embrace Islam. Among the rulings of Islam is the prohibition of a Muslim woman marrying a non-Muslim, and this is a definitive ruling that brooks no debate. Belief in Allah is not complete except by accepting and submitting to His rulings. Whoever objects to a ruling of Allah has gone astray in manifest error. Allah Almighty has permitted marriage only to a Muslim woman or a woman of the Book. Indeed, Allah has wisdom in all His legislations, and the believer submits to Allah's rulings even if he does not comprehend the wisdom behind them. Therefore, monotheism and belief in Allah must be corrected by entering the religion of Islam, which Allah has chosen for His servants.
