On the death of ibn 'Abbad in 995 CE, Abd al-Jabbar was deposed and  arrested by the Buyid Amir, Fakhr al-Dawla, because of a slighting remark made by him about his deceased benefactor. He died later in 415 AH/1025 CE. 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). He argued that the Ash'arite separation between the eternal speech of God and the created words of the Qur'an made God's will unknowable. He and his Mu’tazilite circle were contemporaries of Ibn Sina, better known in the West as Avicenna. Works. He was the author of more than  70 books. Section::::"Tathbit Dala’il". Abd Al-Jabbar produced an anti-Christian polemic text "Tathbit Dala’il Nubuwwat Sayyidina Muhammad," (‘The Establishment of Proofs for the Prophethood of Our Master Mohammed’).
