Through library research methods and psychological approaches, this study shows that the verses of the Qur'an that discuss excessive behavior include the word isrâf with various variations. Some of the variations such as; verbs with fi'il madhi, verbs with fi'il nahyi, verbs with harfu jazmi (lam), ismu fail musrif in mufrad and plural forms. The various uses of the word isrâf in these verses give rise to various interpretations when carried out with a psychological approach. The psychological approach is used in this study, because the authors consider it a relevant and appropriate approach to discussing human behavior, such as excessive behavior.
