Man is a weak being with many inadequacies. He can only lead his life if Allah wills. However, Allah, Who is the Owner of everything, is far removed from all sorts of inadequacies and is exalted above all weaknesses. He is not in need of anything. The Prophet Muhammad (saas) was commanded to speak thus to his nation:

Say: “Am I to take anyone other than Allah as my Protector, the Creator of the heavens and the Earth, He Who feeds and is not fed?” Say: “I was commanded to be the first of the Muslims,” and, “You shall serve no other god besides Him.” Say: “I will never disobey my Lord, for I fear the punishment of a dreadful Day.” (Surat al-An’am, 14-15)

The Prophet Muhammad (saas) told his people that Allah is the One and that He is the sole Possessor of everything.

Say: “Who is the Lord of the heavens and the Earth?” Say: "Allah.” Say: “So why have you taken protectors apart from Him who possess no power even to help or harm themselves?” Say: “Are the blind and seeing equal? Or are darkness and light the same? Or have they assigned partners to Allah who create as He creates, so that all creating seems the same to them?” Say: “Allah is the Creator of everything. He is the One, the All-Conquering.” (Surat ar-Ra’d, 16)
