with several celebrated treatises to his name, such as al-Madkhal (1), al-Zīj (2), al-Ulūf (3), and others, wherein he discusses matters of taysīr (planetary progressions) as well as astrological judgments.
Ibn Khallikān (4) said: “He made astonishingly accurate predictions.” He then related that a certain king was searching for a man who fled and went into hiding. The man, fearing that Abū Maʿshar the astrologer would betray his whereabouts to the king through his craft, took a basin, filled it with blood, placed a mortar beneath it, and sat on that mortar. The king summoned Abū Maʿshar, who cast his sand and scrutinized (5) the affair, then said, “This is remarkable: I see the man seated upon a mountain of gold in the midst of a sea of blood—but this is not in the earthly realm.” He repeated the casting and found the same result. The king, likewise amazed, proclaimed the man’s safety throughout the city. The fugitive emerged; when he stood before the king, the latter asked where he had been hiding, and he explained his stratagem. The people were astonished.
I say: It appears that the knowledge of zajr (augury), ṭuruq (geomantic methods), involuntary twitches of the limbs, and the like—commonly attributed to Jaʿfar ibn Muḥammad al-Ṣādiq—should actually be ascribed to this Jaʿfar ibn Muḥammad, not to al-Ṣādiq. Allah knows best.
[Then the year 273 AH began.]
During it a clash occurred between Isḥāq ibn Kundājiq, governor of Mosul and the Jazirah, and Ibn Abī al-Sāj, governor of Qinnasrīn and other districts, after the two had been allies. Ibn Abī al-Sāj corresponded with Khumarawayh, the ruler of Egypt, and had the Friday sermon in his lands delivered in Khumarawayh’s name. Khumarawayh came to Syria, where Ibn Abī al-Sāj joined him; together they advanced against Isḥāq ibn Kundājiq. Battle was joined, Ibn Kundājiq was routed, and he fled to the fortress of Mardin, where they laid siege to him.
Thereafter Ibn Abī al-Sāj’s fortunes rose; he seized Mosul and the territories of the Jazirah, delivered the khuṭbah there for Khumarawayh, and his power grew tremendously.
In the same year al-Muwaffaq arrested Lu’lu’, a former servant of Aḥmad ibn Ṭūlūn, confiscated four hundred thousand dinars from him, and imprisoned him. He would say, “My only crime is the abundance of my wealth.” He was later released from prison, destitute and humiliated, and returned to Egypt in the days of Hārūn ibn Khumarawayh with only one attendant. Such is the recompense for showing ingratitude toward his master’s favor.
Also that year the sons of the Byzantine emperor rose against their father, killed him, and one of them took the throne afterward.
