Aladdin and the Lamp
Even though he was only a boy, Aladdin got his food by begging on the streets; his father had died, and his mother was very poor. One day a man came to him and said, "Hi Aladdin! I'm your long-lost uncle, and I've come to make you rich!" Aladdin was naturally suspicious, but the man convinced Aladdin's mother, and she gave her permission.
The man took Aladdin to a cave full of jewels and gold, gave him a magic ring, and told him to bring out an old lamp he would find there and give it to him. Aladdin got the lamp, but he refused to give it to the man until the man helped him get out of the cave. Angry, the man trapped Aladdin in the dark cave and left him there.
Alone, scared, and hungry in the cave, Aladdin happened to rub the ring with his hand, and a magic genie came out of the ring and said he would do whatever Aladdin wanted. So Aladdin wished himself home again.
The ring genie told Aladdin that there was another, stronger genie in the lamp, and between the two of them, the genies made Aladdin rich and powerful. He married the Sultan's daughter, and when the evil man eventually came back to try to defeat Aladdin and get the Sultan's daughter for himself, Aladdin (with the help of the genies and his wife, the Princess) defeated him, ended up becoming Sultan, and lived happily ever after.
