In the course of the preparation of the thesis, both primary and secondary sources, which concern Ibn Sina?s philosophy and metaphysics, have been examined and used. The main issues in the thesis are Ibn Sina?s definition and classification of existence, the difference between necessary and possible existence and finally the relationship between God and the Universe. The thesis consists of introduction, three chapters, conclusion and a bibliography. In Introduction, the generation and the development of the philosophical thought within the Turkish-Islamic world are discussed. Besides, in general, the metaphysical thoughts of the Muslim philosophers have also been examined at this chapter. In chapter one, main concepts of Ibn Sina?s metaphysics are given and the tripartite classification of Ibn Sina?s concept of existence is explained in detail. In chapter two, the distinction between `Existence ? Essence?, `Necessary Existence ? Possible Existence? and the essential attributes of the Necessary Being are mentioned. In chapter three, relation of the universe to God, the eternity of the universe, the doctrine of emanation and the theory of reasons are taken into consideration. The process of emanation is invoked to explain the eternity of the universe and source of the other existents within the possible world. As a result, the aim of the thesis is to give an account of the metaphysical doctrine of Ibn Sina with its basic concepts and theories in detail
