Fakhr ad-dīn ar-Rāzī is a very productive scholar who lived in the 12th century, when Islāmic sciences reached their peak, and had a broad scientific acquis enough to write works in almost every scientific field of his age. Mefātīhu al-ghayb, which he wrote in the last period of his life and exhibited all his scientific knowledge, is an extensive volume of work that includes many subjects such as theology, philosophy, Arabic language and rhetoric, fiqh and method, medicine and astronomy. Tafsīr is also important as it contains a significant amount of information about the Arabic language. While interpreting the verses, Rāzī made great use of examples and made important explanations about the science of the Qur’ān. Amthāl al-Qur’ān can be defined as follows: “It is the branch of science that deals with the examples used in the verses to remind the divine truths and explain the message in the minds better.” The science in question, which consists of precedents and the Qur’ān, is more in the field of rhetoric in terms of examples, and more in the field of tafsīr with the dimension of the Qur’ān. Fakhr ad-dīn ar-Rāzī is a scholar who is competent in both fields and produces works. While interpreting the verses and explaining the words in various ways in Rāzī’s tafsīr, it is the aim of the study to determine how he evaluated the examples he discussed in detail between the lines and to determine the explanations on the subject. In a classical work, the descriptive method was mainly applied in the study, since it is based on acquiring knowledge in a specific field. In addition, analytical method was used during the evaluation of the obtained information.
