Tawhid (Islamic Monotheism)
Tawhid or Tauheed (Arabic: توحيد tawḥīd ; English: doctrine of Oneness ; also transliterated Tawheed, and Tauhid) is the concept of monotheism in Islam. It is the religion's most fundamental concept and holds God (Arabic: Allah) as one (wāḥid ) and unique (aḥad ).
The Qur'an asserts the existence of a single and absolute truth that transcends the world; a unique, independent and indivisible being, who is independent of the entire creation. God, according to Islam, is a universal God, rather than a local, tribal, or parochial one—God is an absolute, who integrates all affirmative values and brooks no evil.
Tawhid constitutes the foremost article of the Muslim profession. The first part of the Shahada is the declaration of belief in the oneness of God. To attribute divinity to a created entity, known as shirk, is the only unpardonable sin mentioned in the Qur'an. Muslims believe that the entirety of the Islamic teaching rests on the principle of Tawhid. There is an uncompromising monotheism at the heart of the Islamic beliefs which distinguishes Islam from other major religions.
Islamic intellectual history can be understood as a gradual unfolding of the manner in which successive generations of believers have understood the meaning and implications of professing God's Unity. Islamic scholars have different approaches toward understanding it. Islamic theology, jurisprudence, philosophy, Sufism, even to some degree the Islamic understanding of natural sciences, all seek to explain at some level the principle of tawhid.
