Polytheism is generally widespread among the people and the concept of Monotheism is in scarcity.
Many people who claim to be the bearers of Faith do not understand the meanings ofTauhid (Monotheism) andShirk (polytheism). Apparently they are Muslims, but they are unconsciously involved in the acts ofShirk.
Therefore, first we should try to understand the meanings ofTauhid (Monotheism) andShirk (polytheism) so that we may know about their advantages and disadvantages as directed by Qur'an andSunnah.
