By the orders of the caliph Al-Ma'mun they excavated a new entrance to the object, digging under the original descending corridor. They reached the ascending corridor and the rooms connected with it.
During this period, legends began to appear about the incredible treasures hidden inside the pyramid, and Al-Ma'mun's finding of a vessel filled with thousands of coins. There may be a grain of truth in this story, because Al-Ma'mun may have been trying to relieve the frustration of the workers who dug corridor in the sweat of their brow to get inside the pyramid only to find it looted and therefore he planted the treasure himself.
