The Meaning of the Word of Tawhid (There is no god but Allah)

Question:
How does the word of tawhid (There is no god but Allah) encompass all types of tawhid?

Answer:
Answer: Yes, tawhid is singling out Allah with worship and leaving the worship of anything other than Him. This is the meaning of (There is no god but Allah). (No god) means leaving the worship of anything other than Allah, and (but Allah) means singling out Allah (Exalted and Majestic is He) with worship. Thus, it contains negation and affirmation: the negation of shirk (associating partners with Allah) and the affirmation of tawhid for Allah (Mighty and Majestic). Therefore, it is called the word of (ikhlas) (sincerity) and the firm handhold. (So whoever disbelieves in the Taghut and believes in Allah has grasped the firmest handhold). This is the meaning of (There is no god but Allah). (Disbelieves in the Taghut) is the meaning of (No god), and (believes in Allah) is the meaning of (but Allah). (Has grasped the firmest handhold) is (There is no god but Allah). It is the word of taqwa (mindfulness of Allah), and He commanded them to take hold of the word of taqwa, for they were more deserving of it and its people. It is a great word because of what it contains of tawhid for Allah and His worship, and the negation of worshipping anything other than Him, and the invalidation of worshipping anything other than Allah (Glorified and Exalted is He). And thereby the three types of tawhid are gathered: tawhid al-rububiyyah (oneness of lordship), tawhid al-uluhiyyah (oneness of worship), and tawhid al-asma' wa al-sifat (oneness of the names and attributes).
