His father was Abu'l-Hasan Abbad ibn Abbas (d. 946), a renowned and well-educated administrator, who composed works on the Mu'tazili doctrine. Sahib spent his childhood at Talakan, a town in Daylam near Qazvin. He later settled in Isfahan, and served for some time as an official of the Buyid ruler of Jibal, Rukn al-Dawla (r. 935–976). After the death of his father, Sahib became the pupil of the scholar and philosopher, Ibn 'al-Amid, who had recently replaced Sahib's deceased father as the vizier of Rukn al-Dawla.
