Which state is mentioned by name in the Noble Qur'an, and in which verse is it mentioned?

The Quran mentions kings such as Solomon, Dhul-Qarnayn, and Pharaoh, and these had kingdoms. If the questioner means a state by its title, it is the state of Saba' mentioned in Surat Saba': "There was for Saba' in their dwelling-place a sign: two gardens on the right and on the left. 'Eat of the provision of your Lord, and be grateful to Him. A good land, and a forgiving Lord.'" As for a currently existing state, it is Egypt, which is mentioned in the Quran: "And He said, 'Enter Egypt, Allah willing, in safety!'" and "Is not the dominion of Egypt mine?"
