Introduction Since memorizing Quran has been recommended by the Prophet and Imams, it is expected to see visible effects in the memorizer and his/her life style. Therefore, the aim of this research was to express the degrees of memorizing Quran and to explain the effect of each degree on the human life style based on the teachings of Quran. This research was conducted by a library method, using content analysis approach and reviewing Quranic verses and valid interpretations as well as related narrations in valid narrative books. Conclusion Memorizing Quran, which is emphasized in the verses and traditions, includes memorization of the words of Quran, memorization of the concepts of Quran, memorization of the limits of Quran, and hearty memorization of Quran. Each degree can be an introduction to a higher degree. The impact of each degree of memorization of Quran on life style is different and it is consistent with that degree. Memorizing only the words of Quran does not provide all the benefits mentioned for memorizing Quran and modifies only some of the individual behavioral elements. In the higher degree, memorizing the concepts of Quran influences the individual’ s knowledge and provides the context for behavioral changes and its adaptation to lifestyle based on the teachings of Quran. Memorizing the limits of Quran, which is observing the commandments of Quran, is the adaptation of human behavior to the Quranic doctrines and, in fact, the objective reflect of the Quranic life style. Hearty memorization of Quran, as the highest degree of memorizing Quran, matches the interests, views, and tendencies of man with Quranic principles and shapes the actions and behavior of memorizer and, accordingly, gives him/her the prosperity of the world and Last Day.
