"Afterwards, Hajjaj, during the Khilafat of Walid, son of ‘Abdul malik appointed Muhammad, son of Kasim, son of Muhammail, son of Hakim, son of Abu ‘Ukail to command on the Sindian frontier. Muhammad was in Fars when the order arrived, and had previously received instructions to go to Rai [south of the Caspian Sea]. Abu-l Aswad Jahm, son of Zahru-l Ju’fi, was at the head of the advanced guard, and he was ordered to return to Muhammad, and he joined him on the orders of Sind. Hajjaj ordered six thousand Syrian warriors to attend Muhammad, and others besides. He was provided with all he could require, without omitting even thread and needles. He had leave to remain at Shiraz until all the men who were to accompany him had assembled, and all the preparations had been duly made. Hajjaj had some dressed cotton saturated with strong vinegar, and then dried it in the shade, and said, “When you arrive in Sind, if you find the vinegar scarce, soak the cotton in water, and with the water you can cook your food and season your dishes as you wish.” Some authors say, that when Muhammad arrived on the frontiers, he wrote to complain of the scarcity of vinegar, and this was the reason which induced Hajjaj to send cotton soaked in vinegar."
