35.2.3

It is related by Abul Hasan Hazlí, that "Basáyah and his son Rásil had been on bad terms with Mékah Basáyah for some time past, and their disagreement was too evident. Mékah Basáyah had renounced the cause of Dáhar and had joined Muhammad Kásim, and Rásil, owing to his enmity, proceeded to oppose Mékah and the army of Muhammad Kásim. Mékah ever since the time he had taken in the situation had never submitted or bent his head before Dáhar. He was always favourably inclined to Islám, and sincerely (so inclined). In the war between Dáhar and his enemy, Mékah played dodges and behaved deceitfully and always tried to make Dáhar's cause suffer. Those who had an opportunity to observe his conduct carefully, have related that, when Muhammad Kásim brought the boats and began to link them, Rásil collected the chiefs and nobles of his country, and hastened to the spot in order to prevent the Arabs from making the bridge and crossing the river. Muhammad Kásim, therefore, ordered all the boats to be linked together in a line along the western bank to the length corresponding to the breadth of the river at that place. After this was done, brave warriors armed themselves and put themselves in the boats. Then moving the whole block of boats, keeping one end of it fixed at the crossing-point and turning the other, the head boat was made to touch the opposite point on the eastern bank, and the Arabs, immediately, shot volleys of arrows and drove away the infidels from the bank.
