Islam as a substantive religion that deals with all aspects of life with the total submission to the will of Allah, whose tenets also negate the concept of polytheism' or heterogeneous belief in any form of divinity. This paper aimed at looking into the various beliefs and cultural practices aside the Islamic monotheism (Islamic faith) in Okun, with the view of bringing out the real concept of Islamic monotheism (Tawhid), i.e. oneness of Allah as the major priority from the perspective of The Qu'ran and Hadith, and the scholars' views on the concept of syncretism. The study reveals that there is a prevalence of religious heterogeneity among many Okun .Muslims, and the impact affects them negatively, of which if continuous awareness and campaign against these beliefs were not carried out, this phenomenon will continue among these Muslims. Hence, this research work proffers solutions to such problem. The paper concludes that necessary effort should be intensified by all stakeholders in the area of promoting the effective instillation of practical Tawhid (monotheism) as regards the real teachings of Islamic beliefs.
