Jijak (Arabic: جيجاك) also known as Umm Ali (Arabic: أم علي) was the Turkic Umm Walad of al-Mu'tadid and the mother of the future caliph al-Muktafi.
[1] Jijak Čiček ("flower" in Turkish) was a Turkic slave-girl, who was a concubine of Ahmad ibn Talha, the future caliph al-Mu'tadid.
Al-Mu'tadid also took care to prepare her son Ali, because he was his oldest son and heir-apparent, for the succession by appointing him as a provincial governor: first in Rayy, Qazvin, Qum and Hamadan, when these provinces in c. 894/5, and in 899 over the Jazira and the frontier areas, her son Ali al-Muktafi took up residence at Raqqa.
[citation needed] Jijak became an important and influential Umm walad of the Abbasid harem because of her merit as the mother of elder and nominated heir of al-Mu'tadid.
[citation needed] She died around 900s, before or shortly after her son's ascension to the Caliphate.
