Three Aspects of Tawhid
Scholars of ‘aqeeda divide tawhid into three aspects: tawhid ar-rububiyyah, tawhid al-uloohiyyah, and tawhid al-asmaa wal sifat.
Tawhid Ar-Rububiyyah is the tawhid of Lordship. It pertains to Allah’s right as the Lord, and all that entails–the Creator, the Sustainer.
Tawhid Al-Uloohiyyah is the tawheed of worship. It pertains to Allah’s right to be worshipped, without any partners.
Tawhid Al-Asmaa wal Sifat is the tawheed of Allah’s names and attributes–such as that he is Ar-Rahman and Ar-Rahim.
