The Unity among Muslims is one of the issues noted repeatedly in the Holy Qur'an and other Islamic texts such as Nahj al-Balāghah. It has such as existential, theological, cosmological, anthropological, epistemological and deontological principles. These theoretically justify a thought or an action. However, is no need for expression of all the principles, rather it can be achieved through re-studying their call and practice. In this essay, the relevance and relationship of these principles are surveyed.
