What is tawheed ar-ruboobiyah?

Tawheed ar-Ruboobiyah, or the Oneness of Lordship, refers to the Islamic belief in the existence and singularity of Allah as the sole creator, sustainer, and ruler of the universe. It emphasizes that all things in existence are under His control and authority, affirming that no one shares in His divine power or governance. This concept serves as a foundation for the broader understanding of Tawheed in Islam, highlighting the exclusive nature of Allah's lordship over all creation.
