What is the meaning of the Almighty's saying: (Is not creation and commandment His?)

Allah, the Glorified and Exalted, is the Creator of everything in the universe. His greatness, power, wisdom, knowledge, and might are manifested in His diverse creations. He is the Ever-Living, the Sustainer of all existence, who owns and manages everything, and nothing is beyond His capability. He is All-Capable, creating what He wills however He wills. He is the All-Knowing, the All-Aware, the Subtle, the Generous, the Bountiful, who created humanity and provided for it. Allah has commanded us to worship Him alone, to obey Him and His Messenger (peace be upon him), to adorn ourselves with good morals, and to cooperate in righteousness and piety. For everything, in creation, ownership, and command, is in His hand alone, glorified be He. He alone deserves worship, for He is the Creator, the Sustainer, the All-Knowing, the All-Capable, while all others are helpless and weak.
