A bus full of passengers was on its journey. Suddenly the weather changed and there was a huge downpour and lightning all around. The passengers saw that lightning appeared to strike their bus but then it moved ahead without hitting the bus.
After two or three such instances, the driver stopped the bus about fifty feet away from a tree and said, "We have somebody in the bus whose death is a certainty today. Because of that person everybody else will also get killed. I want each person to go one-by-one and touch the tree trunk and come back. Whosoever’s death is certain will get caught by the lightning and will die. But everybody else will be saved".
