Based on the Islamic sources and using descriptive method and content analysis, this research was conducted with the aim of validating Hazm (prudence) scale. To this end, relevant and reliable Islamic sources were identified, studied, categorized, and conceptualized. After the construction and validation process, the 95-item questionnaire was distributed among 30 university students, seminary students and ordinary people in Qom, who were selected using simple random sampling method. To determine the content validity, the opinions of 8 psychologists - Islamologists were used using content validity index (CVVI and CVR) and Kendall's matching coefficient. To determine face validity, the views of five experts in psychology and Islamic sciences were used. In assessing the reliability of the scale, the Cronbach's alpha coefficient was 0.801 and 0.7868 in the test and re-test stages, respectively. Based on Spearman Brown's split-half coefficient, the internal consistency of the test and re-test was 0.891 and 0.8858, respectively, and based on the Gottman's split-half coefficient, it was 891/0 and 852/0 respectively. The correlation between the two halves of the scale is 0.818 and 0.751, which indicates the strong reliability of the questionnaire.
