Tawhid

Tawhid (Arabic: توحيد‎ tawḥīd, meaning "oneness [of God]" also romanized as tawheed, touheed, or tevhid) is the indivisible oneness concept of monotheism in Islam. Tawhid is the religion's central and single-most important concept, upon which a Muslim's entire faith rests. It unequivocally holds that God is One (Al-ʾAḥad) and Single (Al-Wāḥid); therefore, the Islamic belief in God is considered Unitarian."Tawhid constitutes the foremost article of the Muslim profession of faith.
