Refuting the doubt that the division of tawhid (the oneness of Allah) is a conventional, ijtihad-based matter

Question:
Honorable Shaykh, may Allah grant you success. A questioner from outside this country says: There is a doubt in our country, which is that they say the divisions of tawhid (the oneness of Allah) are matters of ijtihad (independent legal reasoning), so it is permissible to add any division according to need.

Answer:
No, they are not matters of ijtihad (independent legal reasoning); they are taken from the Book and the Sunnah. This is what the people of atheism say; the people of atheism say that this division of tawhid (the oneness of Allah) is conventional. We say: No, it is not conventional; it is taken from the Book and the Sunnah. The verses and hadiths that contain information about Allah and His names and attributes are in tawhid al-rububiyyah (oneness of lordship). The verses that contain the command for the servants to obey Allah and worship Him are in tawhid al-uluhiyyah (oneness of worship). The verses that speak about the names of Allah and His attributes are in tawhid al-asma' wa al-sifat (oneness of the names and attributes). All of this is found in the Qur'an.
