Tawheed, or Islamic Monotheism, is the belief that Allāh (God) is completely unique, without partners or equals in His being, attributes, or right to worship. This core concept teaches that Allāh alone is the Creator, Sustainer, and ultimate Controller of everything in the universe. It also means that all forms of worship—like prayer, trust, and reliance—are directed solely to Allāh, without involving any other beings.
