throne
Masculine noun. Often with the article: الْعَرْشُ. Mentioned about 25 times in the Quran. The Throne is described as the greatest of God's creations.
The ʿArsh (Throne of God) is the greatest creation, above the seven heavens. How God 'rose over' the Throne is accepted without asking 'how' (bilā kayf) in mainstream Islamic theology.
