The Quran says a servant of God rebuilt a wall in an inhospitable town so two orphans could recover their father's buried treasure

Surah 18 of the Quran tells of Moses travelling with a servant of God whose acts he cannot accept. They came to a town and asked its people for food, and the people refused them. They found a wall about to collapse, and the servant repaired it. Moses protested that he could at least have charged a fee. The servant explained before they parted. The wall belonged to two orphan boys of the town. Beneath it was their treasure. Their father had been a righteous man. God willed that the children come of age and retrieve their treasure as a mercy, and the servant said he had not acted on his own. The Quran does not name the servant; Muslim scholars almost all identify him as al-Khidr. The commentator Ibn Kathir cites early authorities who said the treasure was buried wealth, and cites Ibn Abbas that the boys were protected for their father's sake. Scholars have compared the story with a Jewish legend of Elijah and Joshua ben Levi, attested about four centuries later, and with a Greek tale by John Moschus, about 600, in which an angel repairs a wall over buried treasure. The Quran does not say whether the boys recovered it.
