The book “Writings of the Heart” has been a result of longstanding and intensive scientific research of honourable Prof. Dr Hüseyin İlker Çınar. As the subtitle “Sufism and a Noble Character in the light of the Qur’an and the Hadith” implies, the content of the book has been edited in consideration of the primary sources of Islam, the Qur’an and the ahadith. Depending on the specific topics honourable Prof. Dr Hüseyin İlker Çınar provides to the reader a broad view including traditional and modern sources and issuing relevant Islamic scientific disciplines, i.e. doctrines of faith, Sufism, or Islamic jurisprudence. The book outlines an understanding of Sufism in which science and wisdom, sincerity and benevolence, a noble character and thoughtfulness are prime, far from superficiality and superciliousness, purposeful and without harming the Ummah consciousness. Honourable Prof. Dr Hüseyin İlker Çınar issues the problems of Sufi-movements which have been developed under the umbrella of Tarīqa and Sufism apparently to political and business organizations. Moreover, it is presented, how these movements have diverged from the core of Sufism and showing solutions based on the principles of Sufism how to escape from this trap.
