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.

At the end of the year 38, or the beginning of the year 39 H. (659 A.D.) in the Khalifat of Ali, son of Abu Salib, Haras, the son of Marra-I Abdi went with the sanction of the Khalif to the same frontier, as a volunteer. He was victorious, got plunder, made captives, and distributed in one day a thousand heads. He and those who were with him, saving a few, were slain in the land of Kikan in the year 42 H. (662 A.D.) Kikan is in Sind near the frontiers of Khurasan.

In the year 44 H. (664. A.D.), and in the days of the Khalif Mu’awiya, Muhallab, son of Abu Safra made war upon the same frontier, and advanced as far as Banna and Alahwar, which lie between Multan and Kabul. The enemy opposed him and killed him and his followers. In the land of Kikan, Muhallab encountered eighteen Turki horsemen, riding crop-tailed horses. They fought well but were all slain. Muhallab said, “How much more active than we those barbarians were.” So he docked the tails of his horses, and was the first among the Musulmans who did so.
