The one who argued with Abraham

Allah swt said, {Have you not considered the one who argued with Abraham about his Lord because Allah had given him kingship? When Abraham said, “My Lord is the one who gives life and causes death,” he said, “I give life and cause death.” Abraham said, “Indeed, Allah brings the sun up from the east, so bring it up from the west.” So the one who disbelieved was overwhelmed, and Allah does not guide the wrongdoing people.} ¹ What is the interpretation of the above verse? Who is the one who argued with Abraham? Is he the one who disbelieved?
