The main theme of A Ray of the Qur’ān is reflected in Sayyed Mahmoud Taleghani's unique and all-encompassing approach of using root definitions of key Qur’ānic terms as the basis for his illumination of the Qur’ān. Taleghani's method mirrors his thesis that drawing on the light of the Qur’ān along with authentic prophetic tradition, sound theological argument, and a grasp of ethics, science, and human history reveals the observable interconnectedness in nature that exists on an individual and societal level and is constantly evolving as unified creation of one Creator.
The relationship of humanity to the rest of creation as discussed in A Ray of the Qur’ān elicits individual and societal human responsibility to know, care for, preserve, and promote both human society and all of nature in a just, fair, and morally balanced manner. Taleghani holds that the creator of the physical world and its human inhabitants lovingly and justly offers a blueprint and manual for action, and central to that is the Qur’ān. Nonetheless, according to Taleghani’s own humble estimation, his work should not be described as an interpretation, explanation or explication but an effort to allow glimpses of divine guidance to shine on minds and hearts.
A Ray of the Qur’ān will shift the academic discourse around studies of Islam and the Qur’ān, including within Islamic institutions. It offers a compelling and unique approach to theology, comparative religious studies, ethics, environmental studies, and Arabic studies.
