"Each person learns something different. If you wish, I can tell you the story of one such person." Bashaarat proceeded to tell me such a story, and if it pleases Your Majesty, I will recount it here.
There once was a young man named Hassan who was a maker of rope. He stepped through the Gate of Years to see the Cairo of twenty years later, and upon arriving he marveled at how the city had grown. He felt as if he had stepped into a scene embroidered on a tapestry, and even though the city was no more and no less than Cairo, he looked upon the most common sights as objects of wonder.
He was wandering by the Zuweyla Gate, where the sword dancers and snake charmers perform, when an astrologer called to him. "Young man! Do you wish to know the future?"
Hassan laughed. "I know it already," he said.
"Surely you want to know if wealth awaits you, do you not?"
"I am a rope-maker. I know that it does not."
"Can you be so sure? What about the renowned merchant Hassan al-Hubbaul, who began as a rope-maker?"
His curiosity aroused, Hassan asked around the market for others who knew of this wealthy merchant, and found that the name was well known. It was said he lived in the wealthy Habbaniya quarter of the city, so Hassan walked there and asked people to point out his house, which turned out to be the largest one on its street.
He knocked at the door, and a servant led him to a spacious and well-appointed hall with a fountain in the center. Hassan waited while the servant went to fetch his master, but as he looked at the polished ebony and marble around him, he felt that he did not belong in such surroundings, and was about to leave when his older self appeared.
"At last you are here!" the man said. "I have been expecting you!"
"You have?" said Hassan, astounded.
"Of course, because I visited my older self just as you are visiting me. It has been so long that I had forgotten the exact day. Come, dine with me."
The two went to a dining room, where servants brought chicken stuffed with pistachio nuts, fritters soaked in honey, and roast lamb with spiced pomegranates. The older Hassan gave few details of his life: he mentioned business interests of many varieties, but did not say how he had become a merchant; he mentioned a wife, but said it was not time for the younger man to meet her. Instead, he asked young Hassan to remind him of the pranks he had played as a child, and he laughed to hear stories that had faded from his own memory.
At last the younger Hassan asked the older, "How did you make such great changes in your fortune?"
"All I will tell you right now is this: when you go to buy hemp from the market, and you are walking along the Street of Black Dogs, do not walk along the south side as you usually do. Walk along the north."
"And that will enable me to raise my station?"
"Just do as I say. Go back home now; you have rope to make. You will know when to visit me again."
Young Hassan returned to his day and did as he was instructed, keeping to the north side of the street even when there was no shade there. It was a few days later that he witnessed a maddened horse run amok on the south side of the street directly opposite him, kicking several people, injuring another by knocking a heavy jug of palm oil onto him, and even trampling one person under its hooves. After the commotion had subsided, Hassan prayed to Allah for the injured to be healed and the dead to be at peace, and thanked Allah for sparing him.
The next day Hassan stepped through the Gate of Years and sought out his older self. "Were you injured by the horse when you walked by?" he asked him.
"No, because I heeded my older self's warning. Do not forget, you and I are one; every circumstance that befalls you once befell me."
And so the elder Hassan gave the younger instructions, and the younger obeyed them. He refrained from buying eggs from his usual grocer, and thus avoided the illness that struck customers who bought eggs from a spoiled basket. He bought extra hemp, and thus had material to work with when others suffered a shortage due to a delayed caravan. Following his older self's instructions spared Hassan many troubles, but he wondered why his older self would not tell him more. Who would he marry? How would he become wealthy?
Then one day, after having sold all his rope in the market and carrying an unusually full purse, Hassan bumped into a boy while walking on the street. He felt for his purse, discovered it missing, and turned around with a shout to search the crowd for the pickpocket. Hearing Hassan's cry, the boy immediately began running through the crowd. Hassan saw that the boy's tunic was torn at the elbow, but then quickly lost sight of him.
