When I heard this, I was filled with wonder, and said within myself: "I am King Agib, the son of King Khasib, and it was I who threw down the horseman; but, by Allah, I will neither kill him nor do him any injury." Then said I to the youth: "Far from thee be both destruction and harm, if it be the will of God: thou hast nothing to fear: I will remain with thee to serve thee, and will go forth with thee to thy father, and beg of him to send me back to my country, for the which he will obtain a reward." The youth rejoiced at my words, and I sat and conversed with him until night, when I spread his bed for him, and covered him, and slept near to his side. And in the morning I brought him water, and he washed his face, and said to me: "May God requite thee for me with every blessing. If I escape from King Agib, I will make my father reward thee with abundant favours." "Never," I replied, "may the day arrive that would bring thee misfortune!" I then placed before him some refreshments, and after we had eaten together, we passed the day conversing with the utmost cheerfulness. I continued to serve him for nine days; and on the tenth day the youth rejoiced at finding himself in safety, and said to me: "O my brother, I wish that thou wouldst in thy kindness warm for me some water, that I may wash myself and change my clothes; for I have smelt the odour of escape from death, in consequence of thy assistance." "With pleasure," I replied; and I arose, and warmed the water; after which, he entered a place concealed from my view, and, having washed himself and changed his clothes, laid himself upon the mattress to rest after his bath. He then said to me: "Cut up for me, O my brother, a water-melon, and mix its juice with some sugar:" so I arose, and, taking a melon, brought it upon a plate, and said to him; "Knowest thou, O my master, where is the knife?" "See, here it is," he answered, "upon the shelf over my head." I sprang up hastily, and took it from its sheath, and as I was drawing back, my foot slipped, as God had decreed, and I fell upon the youth, grasping in my hand the knife, which entered his body, and he died instantly. When I perceived that he was dead, and that I had killed him, I uttered a loud shriek, and beat my face, and rent my clothes: saying: "This is, indeed, a calamity! O my Lord, I implore thy pardon, and declare to Thee my innocence of his death! Would that I had died before him!"
