One day ten inhabitants of Basra were denounced to Al Mamoun as heretics who held the doctrine of Manes (Manichæans) and the two principles of light and darkness. He ordered them to be brought into his presence. A parasite, who saw them being taken, said to himself: "Here are folk who are going off for a jollification." He slipped in among them, and accompanied them without perceiving who they were till they reached the boat in which their guards made them embark. "Doubtless this is a pleasure party!" he exclaimed, and went on board with them. Soon, however, the guards brought chains and fettered the whole band, including the parasite, who said to himself: "My greediness has ended by making me a prisoner." Then he addressed the seniors of the band: "Pardon me," he said; "may I ask who you are?" "Tell us, rather, who _you_ are," they answered, "and whether we may reckon you among our brothers." "God knows I scarcely know you," he replied. "As for me, to tell the truth, I am a professional parasite. When I left my home this morning I happened to fall in with you. Struck with your agreeable appearance and good manners, I said to myself: 'Here are some well-to-do people going to enjoy themselves.' Consequently I joined your company, and took my place beside you as though I were one of you. When we reached the boat, which was provided with carpets and cushions, and I saw all these bags and well-filled baskets, I thought: 'They are going for an outing in some park or pleasure-ground; this is a lucky day for me.' "I was still congratulating myself when the guards came and fettered you, and me with you. I now feel quite bewildered; tell me, therefore, what it is all about." These words amused the prisoners, and made them smile. They replied: "Now that you are on the list of the suspected, and are chained, know that we are Manichæans who have been denounced to Mamoun, and are being taken to him. He will ask us who we are, will question us concerning our belief, and will exhort us to repent and to abjure our religion, proposing various tests to us; he will, for example, show us an image of Manes, commanding us to spit upon it and to renounce him; he will command us to sacrifice a pheasant. Whoever will do so will save his life; whoever refuses will be put to death. When you are called and put to the test you will say who you are and what your belief is, according as you feel prompted. But did you not say you were a parasite? Now, such people have an ample store of anecdotes and stories; shorten our journey, then, by recounting some." As soon as they arrived at Bagdad the prisoners were conducted into the presence of Mamoun. He called each in turn as his name was on the list; he asked each concerning his sect, and urged them to renounce Manes, showing them his image, and commanding them to spit on it. As they refused, he had them handed over one by one to the executioner.
