 The view of metaphysics as essentially a science of the divine being, rather than of being in general, and the intent of underscoring its affinity, once assimilated with philosophical theology, with Islam, was also characteristic of al-Kindī’s direct disciples and the “school” of authors inspired by his teaching or dependent on his same sources. This is evident both in classifications of the sciences (Qusṭā ibn Lūqā, d. 912; Ibn Farīġūn, 10th century, the Rasāʾil of the Iḫwān al-Ṣafāʾ, written around 961–986; Miskawayh, d. 1030), and in independent treatises related to metaphysics (see Abū Sulaymān al-Manṭiqī al-Siǧistānī, d. ca. 985, and his school; Abū l-Ḥasan Muḥammad ibn Yūsuf al-ʿĀmirī, d. 992).
