Quran 12:72 — Joseph (Yousuf)

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

[12:71] They said, as they came towards them, "What did you lose?"

[12:73] They said, "By GOD, you know full well that we did not come here to commit evil, nor are we thieves."
