When the sultan returned to his palace, he ordered his jewels to be brought out, and the jewelers took a great quantity, particularly those Aladdin had made him a present of, which they soon used, without making any great advance in their work. They came again several times for more, and in a month's time had not finished half their work. In short, they used all the jewels the sultan had, and borrowed of the vizier, but yet the work was not half done. Aladdin, who knew that all the sultan's endeavors to make this window like the rest were in vain, sent for the jewelers and goldsmiths, and not only commanded them to desist from their work, but ordered them to undo what they had begun, and to carry all their jewels back to the sultan and to the vizier. They undid in a few hours what they had been six weeks about, and retired, leaving Aladdin alone in the hall. He took the lamp which he carried about him, rubbed it, and presently the genie appeared. "Genie," said Aladdin, "I ordered thee to leave one of the four and twenty windows of this hall imperfect, and thou hast executed my commands punctually; now I would have thee make it like the rest." The genie immediately disappeared. Aladdin went out of the hall, and returning soon after, found the window, as he wished it to be, like the others. In the meantime, the jewelers and goldsmiths repaired to the palace, and were introduced into the sultan's presence; where the chief jeweler, presenting the precious stones which he had brought back, said, in the name of all the rest, "Your Majesty knows how long we have been upon the work you were pleased to set us about, in which we used all imaginable industry. It was far advanced, when prince Aladdin commanded us not only to leave off, but to undo what we had already begun, and bring your Majesty your jewels back." The sultan asked them if Aladdin had given them any reason for so doing, and they answering that he had given them none, he ordered a horse to be brought, which he mounted, and rode to his son-in-law's palace, with some few attendants on foot. When he came there, he alighted at the staircase, which led up to the hall with the twenty-four windows, and went directly up to it, without giving previous notice to Aladdin; but it happened that at that very juncture Aladdin was opportunely there, and had just time to receive him at the door. The sultan, without giving Aladdin time to complain obligingly of his not having given notice, that he might have acquitted himself with the more becoming respect, said to him, "Son, I come myself to know the reason why you commanded the jewelers to desist from work, and take to pieces what they had done." Aladdin disguised the true reason, which was, that the sultan was not rich enough in jewels to be at so great an expense, but said, "I beg of you now to see if anything is wanting."
