The Chachnāma (Fatḥnāma-yi Sind) 30.4

30.4

As for horses and horsemen, whom you admire so much, they are an army of God. ‘But mind, God has many armies which are most powerful; the league of God and its Judgments are always successful.’ As to what you say about our coming, with armies arrayed for battle, know that that is wholly the result of your wicked deeds and bad manners and vain-glory, for you seized and detained the boats conveying valuable property from Sarandeb, and made the Musalmans prisoners. All the countries of the world acknowledge the rule and superiority of the Khalifah, who is the vicegerent of the Prophet. All pay allegiance to him, while you turn your head from him and rebel against him. All the former rulers and kings regularly paid tribute to his royal treasury, while you have stopped it. As you have thus befouled yourself with ugly manners and unpleasant habits like these, and have swerved from the path of obedience, and have taken such bad behaviour to be unobjectionable, I have received the ever-to-be-obeyed mandate from the Khalifah to exact vengeance for those wicked deeds of yours, and to carry on war with you (to the bitter end). I do hope that, with the help of the great God, who is the most powerful of all, in whatever place you may meet us and oppose us, I shall defeat and degrade you, and ultimately take your head to Irak, or sacrifice my life in the cause of the great God.
