Then Muhammad, son of Kasim, went to old Brahmanabad, two parasangs f rom Mansura, which town indeed did not then exist, its site being a forest. The remnant of the army of Dahir rallied at Brahmanabad and resistance being made, Muhammad was obliged to resort to force, when eight, or as some say, twenty-six thousand men were put to the sword. He left a prefect there. The place is now in ruins.

[During Caliph Hasham bin Abdul Malik (r. 724–43), Sindh military chief Junaid bin Abdur Rahman engaged in a number of victorious campaigns. In his attack of Kiraj, he] ‘stormed the place, slaying, plundering, and making captives.’ ... [After the orthodox Abbasid dynasty was founded in 750, Caliph al-Mansur (r. 755–74) sent Hasham bin Amru for waging holy war against Hindu territories. He] ‘subdued Kashmir and took many prisoners and slaves…’ He then went to Kandahar in boats, and conquered it. He destroyed the budd there, and built in its place a mosque.

The governors who succeeded continued to kill the enemy, taking whatever they could acquire and subduing the people who rebelled. When the fortunate dynasty (that of ‘Abbasides) was established, Abu Muslim appointed ‘Abdu-r Rahman, son of Abu Muslim Mughallisa-l ‘Abdi, to the frontier of Sind. ‘Abdu-r Rahman went by way of Tukharistan, and proceeded against Mansur, son of Jamhur al Kalbi, who was in Sind. But he was met by Mansur and slain, and his forces were put to flight. When Muslim heard this he appointed Musa, son of Ka’bu-t Tamini, and sent him to Sind. When he arrived, the river Mihran lay between him and Mansur, son of Jamhur.17 Still he came up with Mansur, put him and his forces to flight, and slew his brother Manzur. Mansur fled in wretched plight to the sands, where he died of thirst. Musa ruled in Sind, repaired the city of Mansura, and enlarged its mosque. He was victorious in his campaigns.
