Two men sonu and monu were on voyaging ship. The ship wrecked during a storm at sea. Somehow both men were able to swim to an deserted island. Both survivors were good friends, not knowing what else to do, they agreed to just pray to god and find out whose prayer was more powerful. For this they divided the territory between them and stay on opposite sides on island. The first thing they prayed for was food. Next morning sonu saw a fruit bearing tree on his side of island. He ate those fruits and felt good. On the other hand other man side of land remained barren. After a week, sonu felt that he is alone so he prayed for a wife. Again his wish was completed as just next day another ship wrecked and only woman survivor of that ship reached to his part of island. On other hand second man  still had nothing. Finally first man prayed for the ship to rescue himself and his wife and leave the island. Next morning he saw a ship docked at his side of island and boarded the ship with his wife. He decided to leave his friend monu on the island. He considered that he was not worthy to receive god's blessings. Since there was nothing on other side of island sonu concluded that none of his prayer has been answered. As he was about to leave on ship he heard a voice from heavens, "Why are you leaving your friend on island?" Sonu replied, "My blessings are alone, since I prayed for them. his prayers were all unanswered and so he does not deserve anything."Voice replied, "You are mistaken!! he had only one prayer which I answered. if not that, you wouldn't had received any of my blessings." First man asked the voice, "Tell me. what did he pray for that I should owe him anything?"Voice replied, "He prayed that all your prayers be answered." 
For all we know, our blessings are not the fruits of our prayers alone, but those of another praying for us.
