The professor brought him up in his father's palace, and all his years of youth he never left the house, till one day his father clad him in his richest clothes, and mounting him on one of the best of his mules, carried him to the Sultan, who was struck with his beauty and loved him. As for the people of the city, when he passed through the streets on his way to the palace, they were dazzled with his loveliness and sat down in the road, awaiting his return, that they might gaze their fill on his beauty and grace and symmetry. The Sultan made much of the boy and bade his father bring him with him, whenever his affairs called him to the palace. Noureddin replied, "I hear and obey," and ceased not to carry him to the Sultan's court, till he reached the age of fifteen, when his father sickened and calling his son, said to him, "Know, O my son, that this world is but a temporary abode, whilst the next is an eternal one. Before I die, I wish to give thee certain last injunctions, so pay heed to my words and set thy mind to understand them." Then he gave him certain advice as to the proper way of dealing with folk and the conduct of his affairs; after which he called to mind his brother and his native land and wept for his separation from those he loved. Then he wiped away his tears and turning to his son, said to him, "Before I proceed to my parting exhortations, thou must know that thou hast an uncle who is Vizier in Cairo, and I left him and went away without his consent." Then he took a sheet of paper and wrote therein all that had happened to him from the day of the dispute, together with the dates of his marriage and going in to the Vizier's daughter and the birth of his son; after which he folded and sealed the paper and gave it to his son, saying, "keep this paper carefully, for in it is written thy rank and lineage and origin, and if any mishap befall thee, go to Cairo and ask for thine uncle and give him this and tell him that I died in a foreign land, full of longing for him." So Bedreddin took the paper and wrapping it in a piece of waxed cloth, sewed it into the lining of his skull-cap and wound the muslin of his turban over it, weeping the while at the thought of losing his father, whilst himself but a boy. Then said Noureddin, "I have five behests to lay on thee: and the first is that thou be not too familiar with any one, neither frequent him nor foregather with him over-much; so shalt thou be safe from his mischief, for in retirement is safety, and I have heard it said by a poet: There is no man in all the world, whose love is worth thy trust, No friend who, if fate play thee false, will true and constant be. Wherefore I'd have thee live apart and lean for help on none. In this I give thee good advice; so let it profit thee.
