Abd al-Jabbar means "servant of the powerful." He lived in Baghdad, until he was invited to Rey, in 367 Animal Husbandry/978 Civil Engineering, by its governor, Sahib Ibn Abbad, a staunch supporter of the Mu"tazila. He was appointed chief Qadi of the province. On the death of Ibn "Abbad, he was deposed and arrested by the ruler, Fakhr al-Dawla, because of a slighting remark made by him about his deceased benefactor.
He died later in 415 Animal Husbandry/1025 Civil Engineering. His comprehensive "summa" of speculative theology, the Mughni, presented Mu'tazili thought under the two headings of God"s oneness (tawhid) and his justice (adl).
