10.15.5

In the northern courtyard of the mosque is the minaret that has no equal in the lands of Islam. It is built of red stone, unlike the stone of the rest of the mosque, which is white. The stones of the minaret are carved, and it is lofty in height. Its finial is of pure white marble and its apples are of pure gold. Its passage is so wide that elephants can climb it.
