Quote:
{18:77} So they set out, until when they came to the people of a town, they asked its people for food, but they refused to offer them hospitality. And they found therein a wall about to collapse, so al-Khidhr restored it. [Moses] said, "If you wished, you could have taken for it a payment."

{18:77} Then they set out, until when they came to the people of a village, they asked its people for food, but they refused to offer them hospitality. Then they found therein a wall about to collapse, so he (the sage) straightened it up. [Moses] said, "If you wished, you could have taken for it a wage."
