In this article, I explore the response of the Ashʿarī theologian Fakhr al-Dīn al-Rāzī (d. 606/1210) to what can be called “the problem of the efficacy of petitionary prayers” (PEPP), namely the effectiveness of making supplications to God that involve a request for something. The key text I examine is al-Rāzī’s highly dense philosophical work al-Maṭālib al-ʿāliya min al-ʿilm al-ilāhī, in which he outlines his core objections to the efficacy of petitionary prayer and then addresses them directly. In section 1, I include a short historiography of specific English books on the topic of supplications (duʿāʾ) and consider the relevance of al-Rāzī’s response to the issue of their efficacy. In section 2, I outline the preliminaries necessary and relevant for understanding the discussion that follows. In section 3, I survey al-Rāzī’s view on personal prayers. In section 4, I exam­ine in detail al-Rāzī’s formulations of the arguments (from the Maṭālib) that constitute PEPP, with parallel discussions in his huge exegetical work Mafātīḥ al-ghayb. In section 5, I lay out al-Rāzī’s responses to PEPP from the Mafātīḥ in more depth, and draw on theological views from his other works to help support his arguments in the Maṭālib. In the conclu­sion, I evaluate al-Rāzī’s responses and the wider implications they have on a Muslim’s relation to and understanding of God.

The concept of nature (Gr. phúsis; Ar. ṭabīʿa) lies at the heart of classical physics. Seemingly small differences about nature can blossom into significant disagreements. The present study offers an exposition of certain neglected passages concerning ṭabīʿa in Ibn Sīnā’s al-Samāʿ al-ṭabīʿī(The Physics of the Healing). The pre­dominant view of ṭabīʿa is that it as an active principle, a concep­tion of nature that radically departs from Aristotle’s account of phúsis in Physics I-II. I dispute this interpretation by investigat­ing two neglected texts in the Physics of the Healing. First, these texts indicate that nature should be associated with matter and form (I, 6) and, second, they argue that failing to account for matter and form makes knowledge of nature incomplete (I, 9).

In this paper, I examine several commentaries and glosses on the prolegomenon of Najm al-Dīn al-Kātibī’s (d. 675/1276–77) Shamsiyya that relate to debates on the Aristotelian and Ibn Sīnān theory of science in the postclassical period. Chief among the commentaries of the Shamsiyya is Quṭb al-Dīn al-Rāzī’s (d. 766/1365) Taḥrīr al-qawāʿid al-manṭiqiyya. This commentary, rather than the base text of the Shamsiyya, set the stage for later interpretations by Mirak al-Bukhārī (fl. 733/1332), Naṣīr al-Dīn al-Qāshānī (d. 755/1354), Saʿd al-Dīn al-Taftāzānī (d. 792/1390), al-Sayyid al-Sharīf al-Jurjānī (d. 816/1413), Dāwūd al-Khwāfī (fl. 839/1465) and ʿIṣām al-Dīn Isfarāyinī (d. 945/1538). I focus on three issues that were raised in these interpreta­tions of the Shamsiyya’s prolegomenon: (1) the place of the elements of sciences in logical corpus, (2) the notion of the prolegomenon and its content, and (3) the real essence of a science. I attend to the particular debates and contentions on these issues to reveal the general idea of science at that time.
