One day, the Emperor thought of an idea to dupe Birbal. He gave his ring to one of the courtiers and asked him to keep quiet. When Birbal came to the court, the Emperor said to him, "Birbal, look, today I lost my ring! In the morning, it was with . me, but I removed it during my bath. When I came back, I saw that the ring· had disappeared! I am sure that one of the courtiers must have stolen it. I have heard that you are a good astrologer. Now, you must find out the thief. My ring is very precious and as my father had given it to me, it is of great value to me." Birbal said, "Where had you kept the ring before going for the bath?" The Emperor pointed towards a cupboard. Birbal went near the cupboard and placed his ear close to it as if he was hearing something. After some time, Birbal came to the Emperor and said, "The cupboard is saying that there is a small twig in the beard of the person who has stolen the ring." When the courtier with the ring heard Birbal, he touched his heard with fear to examine it. Birbal saw what he did and at once took him before the Emperor and said, "This is the thief!" The Emperor was very pleased with him and gave him a handsome reward.
