Then Muhammad Kasim called his dragoman, and told him: “Ask this man what kindness he did to the prisoners.” The man replied: “Make that enquiry from the prisoners themselves that the real state of things and the truth of my assertion may become known to His Highness.” Thereupon, Muhammad Kasim ordered the prisoners to be brought to him. He then asked them: “What kindness and sympathy has this Kublah shown to you, oh prisoners?” All of them said: “We are much obliged to him. He did all he could to mitigate our misery and to comfort us. He used, at all times, to console us by giving us hopes of the speedy arrival of the army of Islam and of the conquest of Debal.” Muhammad Kasim then called upon him to accept the religion of Islam, and on his agreeing to the proposal Kublah was exalted to the honour of Islam, by his repeating the formula of the Mussalman faith regarding his belief in the unity of God and the prophetship of Muhammad. He was appointed superintendent over the accountants or revenue officers of Debal, who were now ordered to seek his advice in administrative matters, and to render account of the collections as well as of the expenditure to him, while Hamid son of Darad Najdi was made a supervising officer over them all, and the entire administration of the province was entrusted to him.
