Saad and Saleh are brothers living in Najd. God blessed Saad with wealth, while Saleh despite his poverty was blessed with kindness and gentleness that his brother lacked. One day Saleh's sons get sick and he is in a dilemma because he is unable to find medicine for them, so he resorts to the last solution, which is to look for a mythical cave that he heard appears in the desert, where there is a herb that cures all diseases. Saleh visits the cave and succeeds in taking the herb and escapes from the goblin guarding it. Saad hears about the herb, and greedily wants to take a lot of it and sell it at a high price, and in turn, he visits the cave, but he does not have a good attitude with the goblin and does not succeed in surviving his grip.
