Muhammad was the son of Abbasid caliph
Al-Qa'im who reigned from 1031 to 1075 and the grandson of caliph
al-Qadir. His full name was Muhammad ibn Abu Ja'far al-Qa'im ibn Ahmad al-Qadir. He was known in Baghdad as Muhammad Dhakirat. In 1030, his grandfather, al-Qadir named his son Abu Ja'far
al-Qa'im, as his heir, a decision taken completely independently of the Buyīd emirs. During the first half of al-Qa'im's long reign, hardly a day passed in the capital without turmoil. Frequently the city was left without a ruler; the Buyīd emir was often forced to flee the capital. While the
Seljuk influence grew,
Dawud Chaghri Beg married his daughter,
Khadija Arslan Khatun, to al-Qa'im in 1056. His father, al-Qa'im nominated him heir apparent in mid eleventh century however he died during his father's reign and his father then nominated his son, Abdallāh (future
Al-Muqtadi) as next Heir-apparent. In 1075 al-Muqtadi succeeded his grandfather, when al-Qa'im died at the age of 73–74. Al-Muqtadi was born to Muhammad Dhakirat, the son of caliph al-Qa'im, and an
Armenian slave girl called Urjuwuan. ==References==
