Tawhid in Islam refers to the oneness of God, the foundational concept of the Islamic faith. It encompasses three key aspects:Al-Tawhid al-Rububiyyah: Oneness of LordshipâGod is the sole creator, sustainer, and ruler of the universe. No one shares in His power or authority.Al-Tawhid al-Asma' wa al-Sifat: Oneness of Names and AttributesâGod's names and attributes are unique and incomparable, free from human-like qualities.Al-Tawhid al-Uluhiyyah: Oneness of WorshipâOnly God is worthy of worship, and all acts of devotion should be directed to Him alone.Tawhid shapes a Muslim's worldview, emphasizing ethical behavior, accountability, and unity. Violating Tawhid through shirk (associating partners with God) is the gravest sin in Islam. Thus, Tawhid is the essence of Islamic faith, guiding every aspect of a believer's life.
