The holy Qur´an as a miracle, has always been a subject of discussion of the Muslim Theologians.By considering the viewpoints of the Muslim writers such as Shaikh Tabarsi, Seyed Mortaza, Qotb Rawandi, Amin al-Islam Tabarsi, Allamah Majlesi, and Ayatollah Khoei we observe that they have considered the Qur´an as miracle in 2 following aspects:1. Eloquence and literal aspects2. Contents and KnowledgeThe late scholar Mirza Mahdi Isfahani insisted on the contents, sciences, knowledge, and Divine origination of Qur´an as the miracleous aspects. He has explained his view in the treatise "The Miracleous Aspects of the Glorious Word of God". He believed that the miracleous aspects of Qur´an should be looked for in the Qur´an and the words of its true bearers and interpretors.In this article, our writer, by referring to the above work tries to discuss the claims and reasons of Mirza Mahdi Isfahani about the Qur´an as a miracle, the generality and duration of miracleous Qur´an in all ages, the taunts and critiques of disbelievers against the Quranic knowledge; the Divine nature of Qur´an; Qur´an as the best description for guidance, wisdom, and recognition of God.Considering the holy Qur´an as a miracle suits the claim of the holy Prophet as the last Divine Messenger. The main aim of the appointment of the last Messenger and Termination of the Divine Messengers has been to raise the human beings to find the Almighty God by their consciences, to purify their souls, to accomplish and complete their minds; and to notify the Greatness and Purity of the Almighty God.The main reasons of those who have limited the miracleous aspect of Qur´an to eloquence has also been studied, and the approach to hold a wider eye and leave narrow mindedness is to think about the holy verses of Qur´an, and refer to the traditions of the household of the holy Prophet (ahl al-Bayt) peace be upon them.
