Ahmad Jaam was a prominent mystic during fifth and sixth centuries HD having multitude works and profound mystical beliefs which was the basis of a lot of sufi speeches, works such as Resalah Samarghandieh, Serajossaerin, Rozatolmoznebin, Meftahannejat, baharolhaghighah, Ensottaebin, Konoozalhekmah, Fotooharrooh, Letter of belief, Purified, Tazkiraat, and collection of poems, as well as mystical beliefs that this paper is skimming through the mystical expression of Sheikh, including Ikhlas, penitence, monotheism, reliance, samaa', appreciation, patience, love, wisdom, poverty, awareness which are the intellectual reliance of Sheikh. He deemed monotheism as the origin of any activity and penitence as essential for everyone, and the requirement of accepting deeds to be ikhlas. He assumes purified people to have two positions and thinks of reliance to be the kernel of ikhlas and pillar to faith and a bridge to conviction. He approves with samaa' through the Koranic verses and believes that the less wisdom anyone has, the sooner he will fall in love. At last, in terms of poverty "he deems absence in presence" and has divided understanding into public and particular kinds.
