Surah Al-Kahf, Verse 77

Then they went on until they came to the people of a town³⁷. They asked its people for food, but they refused to offer them hospitality. They found there a wall that was about to collapse, but he repaired it. Moses said, “If you wished, you could have taken some payment for it.”

Then they both proceeded, till, when they came to the people of a town, they asked them for food, but they refused to entertain them. Then they found therein a wall about to collapse and he (Khidr) set it up straight. [Mûsâ (Moses)] said: If you had wished, surely, you could have taken wages for it!"

So they twain journeyed on till, when they came unto the folk of a certain township, they asked its folk for food, but they refused to make them guests. And they found therein a wall upon the point of falling into ruin, and he repaired it. (Moses) said: If thou hadst wished, thou couldst have taken payment for it.

Then they proceeded: until, when they came to the inhabitants of a town, they asked them for food, but they refused them hospitality. They found there a wall on the point of falling down, but he set it up straight. (Moses) said: "If thou hadst wished, surely thou couldst have exacted some recompense for it!"

So they went on until when they came to the people of a town, they asked them for food, but they refused to entertain them as guests. Then they found in it a wall which was on the point of falling, so he put it into a right state. (Musa) said: If you had pleased, you might certainly have taken a recompense for it.

So they (both) went off until, when they came up to the population of a city, they asked its population for food, yet they refused to receive them hospitably (i.e. as guests). Then they found therein a wall that would have collapsed down, so he set it up. He said, "If you so decided, indeed you could have taken to yourself a reward for it."
