“Accordingly, after due meditation and without consulting Yussuf, he disguised himself as a dispenser of fodder for camels, secured a rope of silk, four bags and an iron hook. Returning to his home he caused the hook to be covered with soft cloth so that its fall would make no sound, then fastened it to one end of the silken cord and said to Yussuf: ‘Come now and let us try this.’ Yussuf, curious as to what Abou could mean, went with him and together they tried their weight upon it to see if it would hold. Then Abou, learning by observation the hour at night wherein the guards were changed, and choosing a night without moon or stars, disguised himself and Yussuf as watchmen of the city and went to the treasury. Though it was as well guarded as ever they stationed themselves in an alley nearby. And Abou, seeing a muleteer approaching and wishing to test his disguise, ordered him away and he went. Then Abou, watching the guards who were upon the ground meet and turn, and seeing those upon the first tier still in the distance but pacing toward the centre, gave a word to Yussuf and they ran forward, threw the hook over the rim of the first tier and then drew themselves up quickly, hanging there above the lower guards until those of the first tier met and turned. Then they climbed over the wall and repeated this trick upon the guards of the second tier, the third and fourth, until at last they were upon the roof of the cupola where they lay flat. Then Abou, who was prepared, unscrewed one of the plates of the dome, hooked the cord over the side and whispered: ‘Now, master, which?’ Yussuf, ever cautious in his life, replied: ‘Go thou and report.’ “Slipping down the rope, Abou at last came upon a great store of gold and loose jewels piled in heaps, from which he filled the bags he had brought. These he fastened to the rope and ascended. Yussuf, astounded by the sight of so much wealth, was for making many trips, but Abou, detecting a rift where shone a star, urged that they cease for the night. Accordingly, after having fastened these at their waists and the plate to the roof as it had been, they descended as they had come.” “A rare trick,” commented Zad-el-Din. “A treasury after mine own heart,” supplied Al Hadjaz.
