The Cave - 18:82
And the wall belonged to the two orphans of the city. There was a treasure under the wall that belonged to them. Their father was a righteous man. Your Lord willed that when they grew up and became full-grown, they should reveal their treasure as a mercy from your Lord. I did not do these things of my own will. These are the explanations of that which you cannot bear.

Even when you had killed a man, We saved you from sorrow and put you through various tests. Now you have come back, Moses, after many years among the people of Medina, according to a definite plan.
