Ali b. al-Jahm has described one of them in a wonderful poem, saying: Many a dome of a king as if that the stars reveal their secrets to it. The delegations fall down in prostration when it manifests to their eyes. Many a fountain whose flow is (high) in the sky, and it does not fall short of its flowing. It sends back to the rain clouds what they send down to the earth from the direction of their copious shower. When its fire is kindled in Iraq, the brilliance of its light illuminates al-Hijaz.

It has balconies as if that spring had clothed them in gardens through their light.[
