Quran 12:71 — Joseph (Yousuf)

They said, as they came towards them, "What did you lose?"

[12:70] When he provided them with their provisions, he placed the drinking cup in his brother's bag, then an announcer announced: "The owners of this caravan are thieves."

[12:72] They said, "We lost the king's cup. Anyone who returns it will receive an extra camel-load; I personally guarantee this."
