Tawheed

Tawhid (Arabic: تَوْحِيد‎, romanized: tawhid, lit. ’oneness [of God]’) is the concept of monotheism in Islam. Tawhid is the religion’s central and single most important concept, upon which a Muslim’s entire religious adherence rests. It unequivocally holds that God is indivisibly one (ahad) and single (wahid).
