Abu Haritha, the guardian of the treasure-chambers, seeing that they had become empty, waited on Al Mahdi with the keys, and said: "Since you have spent all your treasures, what is the use of my keeping these keys? Give orders that they be taken from me." Al Mahdi replied: "Keep them still, for money will be coming in to you." He then dispatched messengers to all quarters in order to press the payment of the revenues, and in a very short time these sums arrived. They were so abundant that Abu Haritha had enough to do in receiving them and verifying the amount. During three days he did not appear before Al Mahdi, who at length said: "What is he about, that silly Bedouin Arab?" Being informed of the cause which kept him away, he sent for him and said: "What prevented your coming to see us?" "The arrival of cash," replied the other. "How foolish it was in you," said Al Mahdi, "to suppose that money would not come in to us!" "Commander of the Faithful," replied Abu Haritha, "if some unforeseen event happened which could not be surmounted without the aid of money, we should not have time to wait till you sent to have the cash brought in."
It is related that Al Mahdi made the pilgrimage one year, and passed by a milestone on which he saw something written. He stopped to see what it was, and read the following line:
"O Mahdi! you would be truly excellent if you had not taken for a favorite Yakub, the son of Daud."
He then said to a person who was with him: "Write underneath that: 'It shall still be so, in spite of the fellow who wrote that—bad luck attend him!' "On his return from the pilgrimage, he stopped at the same milestone, because the verse had probably made an impression on his mind; and such, in fact, appears to have been the case, for very soon after he let his vengeance fall on Yakub. Rumors unfavorable to this minister had greatly multiplied. His enemies had discovered a point by which he might be attacked, and they reminded the Caliph of his having seconded Ibn Abd Allah the Alide[5] in the revolt against Al Mansur.
One of Yakub's servants informed Al Mahdi that he had heard his master say: "The Caliph has built a pleasure-house, and spent on it fifty millions of dirhems ($6,250,000) out of the public money." The fact was that Al Mahdi had just founded the town of Isabad.
Another time Al Mahdi was about to execute some project when Yakub said to him: "Commander of the Faithful, that is mere profusion." To this Al Mahdi answered: "Evil betide you! does not profusion befit persons of a noble race?"
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.
The girl heard all this conversation, and told a servant of hers to go and relate it to Al Mahdi, and to say in her name: "Such is the conduct of one whom in giving me to him you preferred to yourself; such is the return he makes you for your kindness." Al Mahdi immediately had the road watched, so that the Alide was taken prisoner. He then sent for Yakub, and said to him: "What has become of that man?" Yakub replied: "I have delivered you from the uneasiness he gave you." "Is he dead?" "He is." "Swear by Allah." "I swear by Allah." "Lay your hand upon my head." Yakub did so, and swore by his head. Al Mahdi then said to an attendant: "Boy, bring out to us those who are in that room." The boy opened the door, and there the Alide was seen with the very money which Yakub had given him.
Yakub was so much astounded that he was unable to utter a word. "Your life," said Al Mahdi, "is justly forfeited, and it is in my power to shed your blood, but I will not. Shut him up in the matbak."[6]
