The jewellers and goldsmiths examined the three-and-twenty windows with great attention, and after they had consulted together, to know what each could furnish, they returned, and presented themselves before the sultan, whose principal jeweller undertaking to speak for the rest, said, “Sire, we are all willing to exert our utmost care and industry to obey you; but among us all we cannot furnish jewels enough for so great a work.”  “I have more than are necessary,” said the sultan; “come to my palace, and you shall choose what may answer your purpose.”

When the sultan returned to his palace, he ordered his jewels to be brought out, and the jewellers 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 endeavours to make this window like the rest were in vain, sent for the jewellers 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 mean time, the jewellers and goldsmiths repaired to the palace, and were introduced into the sultan’s presence; where the chief jeweller presented the precious stones which he had brought 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, to inquire why he had ordered the completion of the window to be stopped.  Aladdin met him at the gate, and without giving any reply to his inquiries conducted him to the grand saloon, where the sultan, to his great surprise, found the window, which was left imperfect, to correspond exactly with the others.  He fancied at first that he was mistaken, and examined the two windows on each side, and afterward all the four-and-twenty; but when he was convinced that the window which several workmen had been so long about was finished in so short a time, he embraced Aladdin and kissed him between his eyes.  “My son,” said he, “what a man you are to do such surprising things always in the twinkling of an eye! there is not your fellow in the world; the more I know, the more I admire you.”
