Q38. Once Akbar summoned Birbal and told him that he would have to face death. He asked him to make a statement and if the statement was true he would be buried alive and if the statement was false, he would be thrown at lions.
But, after hearing Birbal’s statement, Akbar could do nothing but smile and awarded him 5 gold coins.
What did Birbal say?
I will be thrown at lions. Now, if Akbar threw him at lions, Birbal’s statement would stand true and he would have to be buried alive. But if he was ordered to be buried, the statement would become false. Thus he was spared and awarded for his wit.
