 Al-Kindī’s main metaphysical treatise (Book on First Philosophy, Kitāb fī l-falsafa al-ūlā, only partially extant) displays monotheistic concerns (the insistence on the theme of God’s unity, with recourse to a model of the God-world relationship reminiscent of the Neoplatonic metaphysics of Theologia Aristotelis and Liber de causis), and the adoption of the doctrine of the creation of the universe in time (derived from Philoponus). The explicit encomiastic references to Aristotle occurring at the beginning (with extensive paraphrastic excerpts of Metaphysics Alpha Elatton) and the abrupt switch to the themes of Book Lambda (albeit treated in an un-Aristotelian vein) confirm that the one-sided theologizing approach to the Metaphysics is directed at showing the compatibility of Greek metaphysics with Islamic religion. Thus, al-Kindī often portrays philosophy in general, and metaphysics in particular, as the discipline deputed to give full articulation and rational explanation to the miraculous conciseness of the prophetic message (besides the central section of On the Quantity of Aristotle’s Books, see also the Epistle on the Explanation of the Prosternation of the Extreme Body and its Obedience to God, Risāla fī l-Ibāna ʿan suǧūd al-ǧirm al-aqṣā wa-ṭāʿatihī li-llāhi).
