What is the response to one who denounces the division of Tawhid into Tawhid of Uluhiyyah, Rububiyyah, and Asma wa Sifat, and says that it is like the division of the Christians, or writes books on that?

The division of Tawhid (Oneness of God) into three categories (Tawhid al-Rububiyyah, Tawhid al-Uluhiyyah, and Tawhid al-Asma wa al-Sifat) is based on the meticulous study and extrapolation of the texts of the Qur’an and Sunnah. It is an elucidation of the meaning of the Oneness of God, not a division of His essence, and it differs from the Christian Trinity. Some scholars have divided Tawhid into two categories: Tawhid of Knowledge and Affirmation (Tawhid al-Rububiyyah), and Tawhid of Seeking and Intention (Tawhid al-Uluhiyyah), including Tawhid al-Asma wa al-Sifat within Tawhid al-Rububiyyah. Tawhid al-Asma wa al-Sifat and Tawhid al-Hakimiyyah (Oneness of God in Rulership) were singled out due to their importance and the prevalence of deviation concerning them. These categories are interconnected and inseparable; Tawhid al-Rububiyyah encompasses Tawhid al-Asma wa al-Sifat and Tawhid al-Hakimiyyah, and Tawhid al-Uluhiyyah includes and necessitates Tawhid al-Rububiyyah.
