‘Abd al-Rahman Jami is known mostly as a poet. Nevertheless, his contribution to Islamic philosophy is also considerable. He was a follower of Ibn Arabi — the founder of the philosophical tasawwuf, whose works were very infl uential in the classic Iranian thought. The philosophy of Jami was outlined in a number of his works, among them are the commentary to the “Fusus al-Hikam” by Ibn Arabi and a short treaty “The commentary to the ruba‘yat” that contains 49 ruba‘i by Jami with his own commentary. This is one of his most important works, explaining the matter of wahdat al-wujud. This article gives an excursus to this treaty, making an accent at the Jami’s interpretation of the necessary being at the context of his epoch of thought. We try to show, that his philosophy, on one hand, deals very much with the works by Ibn Arabi and Suhrawardy, inherits their concepts and problems, so it cannot be properly understood apart from their works. On the other hand, Jami has his own point of view to the philosophy concepts of his teachers. For instance, he gives us a typology of beings, that includes three stages. The fi rst, the lowest one is the stage of a beings whose being is diff erent to their selfness (dhat). They are the things, that surround us every day and passively accept being from an external source. The second one is the being whose selfness is diff erent to its being, but its reality (haqiqa) cannot be seen apart from it. It’s an active matter (the mentioned “source”), that gives being to the beings of the fi rst stage. And the third stage is the simple being, the same to the God’s selfness, that unites the fi rst and the second stages.
