Shiavault - a Vault of Shia Islamic Books The Islamic Concept and Its Characteristics Chapter Ix : the Oneness of Allah We sent no Messenger before you without revealing to him, "There is no god but Me, so worship Me (alone)" (Al-Anbiya 21:25). The Oneness of Allah, known as tawhid, is the first and paramount constituent of the Islamic concept, as it is the fundamental truth of the Islamic faith.
It is also one of the chief characteristics of the Islamic concept because, among all the belief systems and philosophies currently prevailing among human beings, only the Islamic faith can be characterized as having a pure form of monotheism. This is why we have included “The Oneness of Allah" as one of the characteristics of the Islamic concept.
From the outset we state that the message of the Oneness of Allah has been the chief constituent and characteristic of all religions brought by the Messengers of Allah Most High, because every religion sent from Allah was nothing but Islam, which is submission to Allah alone by following the way prescribed by Him alone, receiving guidance in matters of faith and moral conduct from Him alone, purifying one's intention and worship for Him alone, and obeying His commandments and implementing His laws in human affairs as well as in worship.
Unfortunately, after these Messengers passed away, interpolations and deviations were introduced into the pure din of Islam producing many impurities in these religions, so that no belief has been left in its correct and pure form apart from the concept brought by , may Allah's blessings be upon him. Allah Himself has protected the principles of the Islamic faith so that no deviation has ever touched it nor has any impurity ever entered into its beliefs.
This is why “the Oneness of Allah" has become the distinctive characteristic of this faith. The Oneness of Allah is a characteristic of the Islamic concept because the truth of the Divine Oneness includes all aspects of the Islamic faith and practice. It permeates concepts, morals, manners, and all types of dealings among people in a truly Islamic community.
The certainty of the truth that Allah is One dominates the Muslim's concept of the universe and of everything happening in it and his concept of the real, active power behind events in his own life and in the life of the community in which he lives.
