Tafsir of Al-Burooj 85:15

ذو العرش

Owner of the Throne, meaning, the Owner of the Mighty Throne that is above all of the creation. Then He says,

المجيد

Al-Majid (the Glorious). This word has been recited in two different ways: - either with a Dhammah over its last letter (Al-Majidu), which is an attribute of the Lord, or - with a Kasrah under its last letter (Al-Majid), which is a description of the Throne. Nevertheless, both meanings are correct
