The tidings of Khosráu's accession to the throne were received at Sístán by Zál and Rustem with heartfelt pleasure, and they forthwith hastened to court with rich presents, to pay him their homage, and congratulate him on the occasion of his elevation. The heroes were met on the road with suitable honors, and Khosráu embracing Rustem affectionately, lost no time in asking for his assistance in taking vengeance for the death of Saiáwush. The request was no sooner made than granted, and the champion having delivered his presents, then proceeded with his father Zál to wait upon Káús, who prepared a royal banquet, and entertained Khosráu and them in the most sumptuous manner. It was there agreed to march a large army against Afrásiyáb; and all the warriors zealously came forward with their best services, except Zál, who on account of his age requested to remain tranquilly in his own province. Khosráu said to Káús: "The throne can yield no happiness for me, Nor can I sleep the sleep of health and joy Till I have been revenged on that destroyer. The tyrant of Túrán; to please the spirit Of my poor butchered father." Káús, on delivering over to him the imperial army, made him acquainted with the character and merits of every individual of importance. He appointed Fríburz, and a hundred warriors, who were the prince's friends and relatives, to situations of trust and command, and Tús was among them. Gúdarz and his seventy-eight sons and grandsons were placed on the right, and Gustahem, the brother of Tús, with an immense levy on the left. There were also close to Khosráu's person, in the centre of the hosts, thirty-three warriors of the race of Poshang, and a separate guard under Byzun.
