Tawhid al-Hakimiyyah and the study of those who hold it

Question:
Honorable Shaykh, is it permissible to study certain books under the guidance of some shaykhs who classify or record a ruling that falls under the rulings of tawhid (the oneness of Allah), which is the description of the ruling? And is it permissible to study some beneficial books by the later scholars under their guidance?

Answer:
These people claim that this addition is not valid, and it is an addition that has no basis in the Book of Allah or in His covenant. Tawhid al-Hakimiyyah (the oneness of Allah’s sovereignty) is included in tawhid al-uluhiyyah (oneness of worship) in terms of obedience to the Creator, for the created being worships Allah by submitting to His Book and submitting to His commands, Glorified and Exalted is He. It is also included in tawhid al-rububiyyah (oneness of lordship) in that Allah is the One who commands, the One who is free from need, and the One who legislates. Thus, tawhid al-Hakimiyyah is included in tawhid al-uluhiyyah and included in tawhid al-rububiyyah, and it is not an independent category in itself.
If they do not retract this statement, one should not study under them, because they may have other ideas besides this which they teach to those who study under them. If the evidence is established against them and they do not comply, one must seek to study under others. How did we choose the link on the topic? This is, if Allah wills, yes.
