When he was thrown into the sea the Genie made three vows--each in a period of a hundred years. I swore, he says, that "if any man delivered me within the first hundred years, I would make him rich, even after his death. In the second hundred years I swore that if any one set me free I would discover to him all the treasures of the earth; still no help came. In the third period, I swore to make my deliverer a most powerful monarch, to be always at his command, and to grant him every day any three requests he chose to make. Then, being still a prisoner, I swore that I would without mercy kill any man who set me free, and that the only favour I would grant him should be the manner of his death." And so the Genie proposed to kill the fisherman. Now the fisherman did not like the idea of being killed; and he and the Genie had a long discourse about it; but the Genie would have his own way, and the poor fisherman was going to be killed, when he thought of a trick he might play upon the Genie. He knew two things--first that the Jinns are obliged to answer questions put to them in the name of Allah, or God; and also that though very powerful, they are very stupid, and do not see when they are being led into a pitfall. So he said, "I consent to die; but before I choose the manner of my death, I conjure thee, by the great name of Allah, which is graven upon the seal of the prophet Solomon, the son of David, to answer me truly a question I am going to put to thee." Then the Genie trembled, and said, "Ask, but make haste." Now when he knew that the Genie would speak the truth, the Fisherman said, "Darest thou swear by the great name of Allah that thou really wert in that vase?" "I swear it, by the great name of Allah," said the Genie. But the Fisherman said he would not believe it, unless he saw it with his own eyes. Then, being too stupid to perceive the meaning of the Fisherman, the Genie fell into the trap. Immediately the form of the Genie began to change into smoke, and to spread itself as before over the shore and the sea, and then gathering itself together, it began to enter the vase, and continued to do so, with a slow and even motion, until nothing remained outside. Then, out of the vase there issued the voice of the Genie, saying, "Now, thou unbeliever, art thou convinced that I am in the vase?" But instead of answering, the Fisherman quickly took up the leaden cover, and put it on the vase; and then he cried out, "O, Genie! it is now thy turn to ask pardon, and to choose the sort of death thou wilt have; or I will again cast thee into the sea, and I will build upon the shore a house where I will live, to warn all fishermen against a Genie so wicked as thou art."
