al-Muttaqi
Abu Ishaq Ibrahim ibn Jaʿfar al-Muqtadir (Arabic: أبو إسحاق إبراهيم بن جعفر المقتدر) better known by his regnal title al-Muttaqi (908 – July 968, المتقي) was the Abbasid Caliph in Baghdad from 940 to 944.The choice fell on the deceased Caliph's brother al-Muttaqi, who assumed the office after it had been some days vacant; and whose first act was to send a banner and dress of honor to Bajkam, a needless confirmation of his rank.This arrangement did not last long, however: within a few days, the Banu'l-Jarrah brothers were dismissed, and Abu Ishaq Muhammad ibn Ahmad al-Qarariti appointed vizier.[7] In the meantime, a previous amir al-umara, Muhammad ibn Ra'iq, who had fled to Syria, was strengthened by an influx of Turkic commanders leaving Baghdad, and received a letter from al-Muttaqi inviting his return to the Abbasid capital.But, however powerful the Hamdanid chiefs were at home amongst their Arab brethren, and splendid their victories over the Greeks, they found it a different thing to rule at Baghdad, due to foreign mercenaries and the well-organised Turkish forces in the city.
