Birbal helped the poor farmer

 A farmer had bought a well full of water which is near to his farming land by a

 cunning rich man . He bought the well for irrigation purpose .

Next day when the farmer went to water the plants , cunning rich man didn't allow

 him to fetch the water saying that farmer had bought only the well but not the

 water inside it !

Farmer went near Birbal asking for justice . Birbal went near the rich man along

 with farmer .

 Birbal said to rich man ," According to you , you have only sold the well but

 not the water inside of it . So , now you have to take out all the water

 inside the well . If you failed to do it , then you have to pay rent to my

 client for allowing to keep your water inside the well of my client !! "

Now rich man realised his game is over and allowed the farmer to use the water .
