Note 131 — Chapter IV · GENESIS OF THE EARLY MOHAMMADAN PALACE
Reading edition
Balâdhuri (Futûḥ, p. 288) says that Ibrahîm ibn Salamah, one of the chiefs of Khurâsân, built the dome of the old Persian palace of Khawarnaq, in the khalifate of Abu Abbâs, and adds that previously there was no dome there. Possibly the domes seen by Ibn Baṭûṭah were due to this Mohammadan restoration.
