"Mansur, son of Hatim, related to me that Fazl, son of Mahan, formerly a slave of the sons of Sama, got into Sindan and subdued it. He then sent an elephant to the Khalif Mamun, and wrote to him and offered up prayers for him in the Jami’ masjid, which he built there. When he died he was succeeded by Muhammad, son of Fazl, son of Mahan. He proceeded with seventy vessels against the Meds of Hind. He killed a great number of them, captured Kallari25(?) and then returned towards Sindan. But his brother, named Mahan, had made himself master of Sindan, and wrote to the Khalif Mu’tasim bi-llah, and had sent to him as a present the largest and longest saj26, that [p. 31] had been seen. But the Indians were under the control of his brother whom they liked. So they slew Mahan and crucified him. The Indians afterwards made themselves masters of Sindan, but they spared the mosque, and the Muhammadans used to meet in it on Friday and pray for the Khalif."
