When Djerir came into Abu Muslim's presence, he addressed him as follows: "My lord, you have fought hitherto faithfully for the Abbassides (Al Mansur's family); why should you now turn against them? No information has reached the Caliph which should inspire you with any sort of fear; you have really, in my belief, no reason to pursue this line of conduct." Abu Muslim was on the point of promising to return with him, when one of his intimates pressed him not to do so. "My friend," the chief answered him, "I can resist the suggestions of the devil, but not those of a man like this." And in fact Djerir did not cease his persuasions till he had induced him to proceed to the Caliph. Abu Muslim had consulted astrologers, who told him that he was to destroy a dynasty, create a dynasty,[1] and be slain in the land of Rum (Asia Minor). Al Mansur was then at Rumaiyat al-Madain, a place founded by one of the Persian kings, and Abu Muslim never suspected that he should meet with his death there, as he fancied that it was Asia Minor which was meant by the oracle. On entering into Al Mansur's presence, he met with a most favorable reception, and was then told to retire to his tent; but the Caliph only waited a favorable opportunity to take him unawares. Abu Muslim then rode a number of times to visit Al Mansur, whose manner appeared less cordial than before. At last he went to the palace one day, and, being informed that the Caliph was making his ablutions previously to his prayers, sat down in an antechamber. In the meanwhile Al Mansur had posted some persons behind a curtain near to the sofa where Abu Muslim was sitting, with the orders not to appear till the Caliph clapped his hands. On this signal they were to strike off Abu Muslim's head. Al Mansur then took his seat on the throne, and Abu Muslim, being introduced, made his salutation, which the Caliph returned. Al Mansur then permitted him to sit, and, having commenced the conversation, proceeded to level sundry reproaches against him. "Thou hast done this," said he, "and thou hast done that." "Why does my lord speak so to me," replied Abu Muslim, "after all my efforts and services?" "Son of a prostitute!" exclaimed Al Mansur, "thou owest thy success to our own good fortune. Had a negress slave been in thy place, she would have done as much as thou! Was it not thou who soughtest to obtain in marriage my aunt, Aasiya, pretending indeed that thou wast a descendant of Salit, the son of Abd Allah Ibn Abbas? Thou hast undertaken, infamous wretch! to mount where thou canst not reach."
