The oneness of God in His Lordship means that God, The Originating Creator of the Heavens and the Earth, has absolute and perfect mastery over the universe. He alone is The Creator of all things. He alone causes everything to happen. He is The One who provides all sustenance and who determines all life and death. He is The Powerful, The Omnipotent, absolutely perfect and free from any defect. No one shares in His dominion. None can resist His decree. He is The One who created each of us from a single cell and made us into what we are. He is The One who created over a hundred billion galaxies and every electron, neutron, and quark contained within them, keeping all that exists and all the laws of nature in perfect measure. Not a leaf falls from a tree without His permission. Everything is kept in a precise record.
He is far greater than our imagination. He is so powerful that for anything to be created He simply says “Be,” and it is. He created time, space, and all the known and unknown worlds, yet He is not part of any of them. Most faiths recognize that The Creator of the universe is one, without partner. Islam includes the knowledge that God is not a part of His creation and none of His creation shares in His power.
In Islam, to believe that any of God’s creation shares in His power or attributes is considered polytheism and disbelief. Examples of such false beliefs would be to consider that fortune-tellers or astrologers can predict the future; God, The All Aware, says that only He possesses the knowledge of the future. Only the Divine can give divine help. No being except God has the ability to give divine help or divine guidance. Belief that good luck charms and talismans have any power is a form of polytheism. These concepts are renounced in Islam.
