Therefore, when Ali Baba went to the cave again to take some more money, his brother followed him. He saw everything and decided to go back the next day to take some money for himself. The next morning, he found a lot of money in the cave, and he wanted to take all of them. Unfortunately, when he was busy carrying the money to his house, the thieves came. The boss of the thieves asked him how he knew about the cave. He told everything, but unluckily they killed him and went to Ali Baba’s house.
