A weak fisherman caught a strong fish in his net and not being able to retain it the fish overcame him and pulled the net from his hand.

A boy went to bring water from the torrent.
The torrent came and took the boy away.
The net brought every time a fish.
This time the fish went and carried off the net.

The other fishermen were sorry and blamed him for not being able to retain such a fish which had fallen into his net. He replied: ‘O brothers, what can be done? My day was not lucky but the fish had yet one remaining. ‘Moral: A fisherman cannot catch a fish in the Tigris without a day of luck and a fish cannot die on dry ground without the decree of fate.
