Quran 12:73 — Joseph (Yousuf)

They said, "By GOD, you know full well that we did not come here to commit evil, nor are we 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."

[12:74] They said, "What is the punishment for the thief, if you are liars?"
