Once a man sold his well to a farmer. Next day when a farmer went to draw the water from that well.the man did not allow him to draw the water from it. He said, I have sold you the well, not the water, so you
cannot draw the water from the well.
The farmer became very sad and came to the Emperor's court. He described everything to the emperor
and asked for the justice. The emperor called Birbal and handed over this case to him. Birbal called the man
who sold the well to the farmer. Birbal asked, "why don't you let him use the water of the well. You have
sold the well to the farmer." The man replied, "Birbal I have sold the well to the farmer, not the water. He
has no right to draw the water from the well." Then Birbal smiled and said to him, "Good, but look, since you
have sold the well to this farmer, and you claim that the water is yours. Then you have no right to keep your
water in the farmer's well. Either you pay rent to the farmer to keep your water in his weil, or you take that
out of his weil immediately. The man understood that his trick has failed. Birbal has outwitted him.
