The word Shariah is an Arabic word, which literally means path to a water place or path to be followed. It denotes the body of those institutions which Allah ordained in full or essence to guide individual but the path by all Muslims to be the path shown by Allah, the creator himself through his Messenger, Prophet Muhammad (SAW) in their relationship with Allah, and their fellow Muslim and the rest of the universe. Shariah therefore, in its broader sense is the totality of man of Allah’s commandments covering all human aspect of life of a believer or collective believers and indeed entire universe, containing in all ability of guidance to ethics and fundamentally a code of conduct ordained to regulate human conduct to a successful result both here and in the hereafter. This paper discusses the application of Shariah in Nigeria. It was established and enforced in the Northern part of country and in the part of Yoruba land before the British colonized the whole country. Shariah has been part and parcel of Muslim life in the North.
