What is the explanation of the text: "He is the First, so there is nothing before Him. And the Last, so there is nothing after Him. And He is the Manifest, so there is nothing above Him. And He is the Immanent, so there is nothing below Him"?

The meanings of Allah's Beautiful Names "The First, The Last, The Manifest, The Intimate (Hidden)" as mentioned in the Prophet's supplication (peace be upon him) are: The First: The Eternal, without beginning; The Last: The Everlasting, who does not perish; The Manifest: The Exalted, above His creation; and The Intimate (Hidden): The One who is close to them and knows what is hidden. It was also said regarding The Intimate (Hidden) that He is concealed from His creation or the One who knows what is concealed.
