This definition encompasses Tawḥīd al-Rubūbiyyah, Tawḥīd al-Asmāʾ wa-l-Ṣifāt, and Tawḥīd al-Ulūhiyyah.
For this reason, it is often called Tawḥīd al-ʿIbādah (Oneness of Worship), emphasizing the practical dimension of singling out Allah in all devotional acts.
Together, these form the balanced methodology of affirmation without anthropomorphism and transcendence without denial.
Thus, affirming worship of Allah alone was the central mission of revelation, the purpose for which messengers were sent and scriptures revealed.
Together, they ensure both inward purity and outward devotion, accounting for worship that is complete, accepted, and pleasing to Allah.
The Principle: Lordship belongs entirely to Him; worship belongs entirely to Him from His servants. These two cannot be separated.
