A speaker among them said, “How long have you stayed?” They said, “We have stayed a day, or part of a day.” They said, “Your Lord knows best how long you have stayed.” “Send one of you to the city, with this money of yours, and let him see which food is most suitable, and let him bring you some provision thereof. And let him be gentle, and let no one become aware of you.”

18:77So they set out. Until, when they reached the people of a town, they asked them for food, but they refused to offer them hospitality. There they found a wall about to collapse, and he repaired it. He said, “If you wanted, you could have obtained a payment for it.”
