Tawhid (monotheism) is the greatest favour of Allah on humanity. Islam is a substantive religion that deals with all aspects of life with 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 to look into the various beliefs and cultural practices aside from Islamic monotheism (Islamic faith) in Igala, with a view to bringing out the real concept of Islamic monotheism (Tawhid), i.e., the oneness of Allah, as the major priority from the perspective of the Qur'an and Hadith and the scholars' views on the concept of syncretism. The study reveals that there is a prevalence of religious heterogeneity among many Igala Muslims and the impact affects them negatively; if a continuous awareness and campaign against these beliefs is not carried out, this phenomenon will continue among these Muslims. Hence, this research work is a possible outcome and solution. The paper concludes that the 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.
