Sulaiman and Isa, having made inquiries about their secretary, were informed that he had gone into the palace of Sofyan in good health and that he had not come out. They therefore cited Sofyan before Al Mansur, and brought him with them in chains. Witnesses were produced, who declared that they saw Ibn al Mukaffa enter Sofyan's palace, and that he never came out after, and Al Mansur promised to examine into the matter. He then said to them: "Suppose that I put Sofyan to death in retaliation for the death of Ibn al Mukaffa, and that Ibn al Mukaffa himself then came forth from that door" (pointing to one which was behind him) "and spoke to you—what should I do to you in that case? I should put you to death in retaliation for the death of Sofyan." On this the witnesses retraced their evidence, and Isa and Sulaiman ceased to speak of their secretary, knowing that he had been killed by order of Al Mansur, who, disregarding his promise, cast Abdallah Ibn Ali into prison. Terrible as was the wrath of Al Mansur when roused, there were not wanting on occasion those among his subjects who had the courage to rebuke him. Once the Caliph was addressing an audience at Damascus, and said: "O ye people! it is incumbent on you to give praise to the Most High that he has sent me to reign over you. For verily since I began to reign over you, he has taken away the plague which had come amongst you." But a certain Arab cried out to him: "Of a truth Allah is too merciful to give us both thee and the plague at one time!" On another occasion the theologian Malik Ibn Anas relates the following: "One day the Caliph Mansur sent for me and my friend Ibn Taous, against whom he was known to entertain a grudge. When we entered the presence-chamber, we beheld the executioner with his sword drawn and the leather carpet spread, on which it was customary to behead criminals. The Caliph signed to us to seat ourselves, and when we had done so he remained a long time with his head bent in meditation. He then raised it, and turning to Ibn Taous, said: 'Recite me a saying of the Prophet, on whom be peace.' "Ibn Taous replied: 'The Prophet of God has said, "The worst punished criminals in the day of judgment will be those to whom God has entrusted authority and who have abused it."' The Caliph was silent, and there was a pause. I trembled, and drew my garments close round me, lest any of the blood of Ibn Taous, whom I expected to see instantly executed, should spurt upon them. "Then the Caliph said to Ibn Taous: 'Hand me that ink-pot.' But he never stirred. 'Why don't you hand it?' asked the Caliph. 'Because,' he said, 'I fear you may write some wrong order, and I do not wish to share the responsibility.' 'Get up and go,' the Caliph growled. 'Precisely what we were desiring,' answered Ibn Taous, of whose courage and coolness I from that day formed a high opinion."
