Allam Tabatabai's Point of View about the Meaning of “MA 'roof” and its Effect on the Rule of MA 'roof Behavior and the Interpretation of Article 1103 of the Civil Code

The main source of the rule of "MA 'roof" in Qur'an is the Qur'anic order of "Wa Ashruhan Ba-MA 'roof " meaning "live with MA 'roof". The word of "MA 'roof" which is used several times in the Qur'an, had been considered to mean conventional behavior by Allam Tabatabai. What confirms this view is the contrast established in the Qur'an between MA 'roof behavior and Ẓerari or (harmful) behavior. The result of this point of view is that in marital life, creating an executive guarantee and legal responsibility for leaving the MA 'roof behavior and good behavior is conditional on an unconventional behavior or Ẓerari behavior. So, according to the above rule of Article 1103 of the Civil Code, the obligation contained in this rule would be a legal obligation and has a guarantee of execution only when the abandonment of good behavior leads to harmful and unconventional behavior or to Noshouz. In this research, based on the view of Allam Tabatabai about the MA 'roof word and its jurisprudential and legal works, after collecting the sources in a library style, the conceptual analysis of the data has been done with a descriptive method.
