After the wedding had taken place Aladdin led her into the hall, where a feast was spread, and she supped with him, after which they danced till midnight. Next day Aladdin invited the Sultan to see the palace. On entering the hall with the four-and-twenty windows, with their rubies, diamonds, and emeralds, he cried: "It is a world's wonder! There is only one thing that surprises me. Was it by accident that one window was left unfinished?" "No, sir, by design," returned Aladdin. "I wished your Majesty to have the glory of finishing this palace." The Sultan was pleased, and sent for the best jewelers in the city. He showed them the unfinished window, and bade them fit it up like the others. "Sir," replied their spokesman, "we cannot find jewels enough." The Sultan had his own fetched, which they soon used, but to no purpose, for in a month's time the work was not half done. Aladdin, knowing that their task was vain, bade them undo their work and carry the jewels back, and the genie finished the window at his command. The Sultan was surprised to receive his jewels again, and visited Aladdin, who showed him the window finished. The Sultan embraced him, the envious Vizier meanwhile hinting that it was the work of enchantment.

Aladdin had won the hearts of the people by his gentle bearing. He was made captain of the Sultan's armies, and won several battles for him, but remained modest and courteous as before, and lived thus in peace and content for several years.

But far away in Africa the magician remembered Aladdin, and by his magic arts discovered that Aladdin, instead of perishing miserably in the cave, had escaped, and had married a princess, with whom he was living in great honor and wealth. He knew that the poor tailor's son could only have accomplished this by means of the lamp, and traveled night and day until he reached the capital of China, bent on Aladdin's ruin. As he passed through the town he heard people talking everywhere about a marvellous palace. "Forgive my ignorance," he asked, "what is this palace you speak Of?" "Have you not heard of Prince Aladdin's palace," was the reply, "the greatest wonder of the world? I will direct you if you have a mind to see it." The magician thanked him who spoke, and having seen the palace, knew that it had been raised by the Genie of the Lamp, and became half mad with rage. He determined to get hold of the lamp, and again plunge Aladdin into the deepest poverty.

Unluckily, Aladdin had gone a-hunting for eight days, which gave the magician plenty of time. He bought a dozen copper lamps, put them into a basket, and went to the palace, crying: "New lamps for old!" followed by a jeering crowd. The Princess, sitting in the hall of four-and-twenty windows, sent a slave to find out what the noise was about, who came back laughing, so that the Princess scolded her. "Madam," replied the slave, "who can help laughing to see an old fool offering to exchange fine new lamps for old ones?" Another slave, hearing this, said: "There is an old one on the cornice there which he can have." Now this was the magic lamp, which Aladdin had left there, as he could not take it out hunting with him. The Princess, not knowing its value, laughingly bade the slave take it and make the exchange. She went and said to the magician: "Give me a new lamp for this." He snatched it and bade the slave take her choice, amid the jeers of the crowd. Little he cared, but left off crying his lamps, and went out of the city gates to a lonely place, where he remained till nightfall, when he pulled out the lamp and rubbed it. The genie appeared, and at the magician's command carried him, together with the palace and the Princess in it, to a lonely place in Africa.

Next morning the Sultan looked out of the window toward Aladdin's palace and rubbed his eyes, for it was gone. He sent for the Vizier and asked what had become of the palace. The Vizier looked out too, and was lost in astonishment. He again put it down to enchantment, and this time the Sultan believed him, and sent thirty men on horseback to fetch Aladdin in chains. They met him riding home, bound him, and forced him to go with them on foot. The people, however, who loved him, followed, armed, to see that he came to no harm. He was carried before the Sultan, who ordered the executioner to cut off his head. The executioner made Aladdin kneel down, bandaged his eyes, and raised his scimitar to strike. At that instant the Vizier, who saw that the crowd had forced their way into the courtyard and were scaling the walls to rescue Aladdin, called to the executioner to stay his hand. The people, indeed, looked so threatening that the Sultan gave way and ordered Aladdin to be unbound, and pardoned him in the sight of the crowd. Aladdin now begged to know what he had done. "False wretch!" said the Sultan, "come thither," and showed him from the window the place where his palace had stood.
