At last Yakub got so tired of the post which he filled that he requested of Al Mahdi permission to give it up, but that favor he could not obtain. Al Mahdi then wished to try if he was still inclined toward the party of the Alides, and sent for him, after taking his seat in a salon of which all the furniture was red. He himself had on red clothes, and behind him stood a young female slave dressed in red; before him was a garden filled with roses of all sorts. "Tell me, Yakub," said he, "what do you think of this salon of ours?" The other replied: "It is the very perfection of beauty. May God permit the Commander of the Faithful to enjoy it long!" "Well," said Al Mahdi, "all that it contains is yours, with this girl to crown your happiness, and, moreover, a sum of one hundred thousand dirhems" ($12,500). Yakub invoked God's blessing on the Caliph, who then said to him: "I have something to ask of you." On this, Yakub stood up from his seat, and exclaimed: "Commander of the Faithful, such words can only proceed from anger. May God protect me from your wrath." Al Mahdi replied: "I wish you to promise to do what I ask." Yakub answered: "I hear, and shall obey." "Swear by Allah," said the Caliph. He swore. "Swear again by Allah." He swore. "Swear again by Allah." He swore for the third time, and the Caliph then said to him: "Lay your hand on my head and swear again." Yakub did so. Al Mahdi, having thus obtained from him the firmest promise that could be made, said: "There is an Alide, and I wish you to deliver me from the uneasiness which he causes me, and thus set my mind at rest. Here he is; I give him up to you." He then delivered the Alide over to him, and bestowed on him the girl, with all the furniture that was in the salon and the money. When the Alide was alone with him, he said: "Yakub, beware lest you have my blood to answer for before God. I am descended from Fatima, the daughter of Mohammed, on whom God's blessings and favors always repose." To this Yakub replied: "Tell me, sir, if there be good in you." The Alide answered: "If you do good to me, I shall be grateful and pray for your happiness." "Receive the money," said Yakub, "and take whatever road you like." "Such a road," said the Alide, naming it, "is the safest." "Depart with my good wishes," said Yakub.
