This stone’s origin is related to the legend of a sultan nicknamed “Ben” who searched for the gates of the sand palace. Ben has been walking for days in the desert, under a blazing sun. Thirsty and exhausted, he ends up in the middle of a sandstorm that makes him lose consciousness. At that moment, something strange happens. The sandstorm opens to let a strange silhouette pass through, gently putting a water gourd near the sultan.
