The Meaning of Tawhid and Its Types

Question:
Honorable Shaykh, this questioner says: What is the meaning of tawhid (the oneness of Allah)? How many types is it divided into? And what is the definition of each type, O Shaykh?

Answer:
Tawhid is singling out Allah (Exalted and Majestic is He) in worship. This is tawhid. Allah (Exalted and Majestic is He) said: He the Exalted said: So it is singling out Allah in worship and abandoning the worship of anything other than Him. Its types are three: tawhid al-rububiyyah (oneness of lordship), which is singling out Allah in His actions, such as creation, provision, giving life, and causing death, and other matters that no one can do except Allah. The second is tawhid al-uluhiyyah (oneness of worship) and tawhid of worship, which is singling out Allah (Exalted and Majestic is He) with the actions of the servants that He has legislated for them to single Him out with, such as supplication, prayer, fasting, Hajj, and 'Umrah, and all good deeds. They single out their intention in them for Allah (Mighty and Majestic), and they do not seek with them any worldly desire, nor do they seek with them showing off or fame. And more severe than that, they do not associate anything with Allah in His worship (Glorified and Exalted is He).
And tawhid al-asma' wa al-sifat (oneness of the names and attributes) is that we describe Allah (Exalted and Majestic is He) with what He named Himself with and what He described Himself with, from the names of Allah and His attributes that have come in the Book and the Sunnah. He the Exalted said: Yes.
