The Status of Tawhid and the Concept of Worship

Question:
Also, given the greatness of tawhid (the oneness of Allah), the brother Abu Khalid asks about the status of tawhid among all other acts of worship, along with an explanation of its virtue, and what is the concept of worship in Islam?

Answer:
Tawhid (the oneness of Allah) is the first pillar of the pillars of Islam: the testimony that there is no god but Allah and that Muhammad is the Messenger of Allah. The testimony that there is no god but Allah means that none is to be worshipped except Allah (Glorified and Exalted is He). There is no deity worthy of worship except Allah (Glorified and Exalted is He). This is the meaning of the testimony that there is no god but Allah: there is no deity worthy of worship except Allah. As for the testimony that Muhammad is the Messenger of Allah, its meaning is to acknowledge his message, follow him, and take him as a model (peace and blessings be upon him). Yes.
