Ibrahim ibn al-Mudabbir

Vizier Ubayd Allah ibn Khaqan, threatened by the two brothers, caused both to be overthrown and imprisoned in 854/5.

[1] Unlike his brother, he remained in prison for several years; it is unknown when he was set free and was appointed tax-collector in Ahwaz.

[1] In 882, he accompanied Caliph al-Mu'tamid (r. 870–892) in his attempted flight to join Ahmad ibn Tulun, and was briefly appointed his vizier.

[1] He was in all likelihood the author of a treatise on administration, al-ʿAdhrāʾ fi mawāzīn al-balāgha wa adawāt al-kitāba.

Anecdotes concerning him, as well as several of his poems, including some dedicated to the famous singing girl Arib, survive in various medieval collections.
