The Eclecticism of Proofs on the Road to Demonstrate The Existence of Allah: Examples of Dawwānī and Aḥmad Nūrī

The most fundamental subject and aim of the Islamic belief system is the subject of maʿrifatullah (knowing Allah). Studies on this subject are mostly called ithbāt al-wājib (the demonstration of God) in the literature. They are considered the most valuable work for kalām, philosophy and mysticism schools. Kalām schools started to use this conceptualization intensively after Fakhr al-Dīn al-Rāzī, mainly under the influence of Ibn Sīnā. Sūfis, on the other hand, most participated in these studies based on the theory of the unity of existence. In kalām, all the principles of belief are ultimately grounded to explain and strengthen faith in Allah. For this reason, belief in Allah is referred to as aṣl al-uṣūl (the origin of all principles). Throughout history, scholars of kalām discussed the creedal issues of Islam in the Muslim society while it tried to answer the creedal issues abroad by the expanding Islamic geography with studies on ithbāt al-wājib. In this framework, the problems of prophecy and the hereafter are included in kalām. Since the beginning of the history of kalām, it has used the theory of atomism to a large extent, especially in defending the existence of Allah against materialists. The systematisation of Islamic philosophy and mysticism in time, the kalām cosmological argument, the argument from contingency of philosophers and the argument from kashf and ilhām of Sūfis strengthened this area from three different branches. On the other hand, the interaction of these schools within themselves and the diversification of the interlocutors of studies on ithbāt al-wājib brought these arguments closer together. The convergence in terms of terminology, subject and methodology, especially after Shahrestānī and Rāzī, revealed the tradition of philosophical theology. In this process, theologians began to use both the concepts of temporality (hudūth) and contingency (imkān) to use ontological, cosmological and teleological proofs. Dawānī, one of the eminent figures of these studies in the last periods of Ottomans, is the subject of our research, due to his skills in utilising these proofs of ithbāt al-wājib and his influence in the studies after him. His review of the matter can be observed in his effort in his works where he deals with the so-called deficiencies and errors of his predecessors regarding ithbāt al-wājib. For this reason, many annotations and commentaries were made for his treatises and ideas until the 19th century. Especially, the advance of materialism in the West in this century showed great influence on many scholars and intellectuals in the Ottoman Empire seems to be a parallel historical experience. Therefore, it has become necessary to utilise the arguments for the existence of Allah by supporting each individual argument together. In this regard, in our study, to see the process, we also discussed the views of Aḥmad Nūrī, one of the scholars in the last period Ottoman, who dealt with the common arguments about ithbāt al-wājib produced by the three primary schools of Islamic thought: kalām, Islamic philosophy and mysticism.
