One of the prevalent commentary rules about commentary of the historical verses which has a certain revelation occasion and refers to a specific time and place is the rule of alibrah being stated as: take in consideration universality of the word not particularity of the occasion. The source of this rule refers to the verses which have universal word and particular occasion. The referent of the rule is also a kind of generalization in the commentary of the verse based on the need to departure from revelation case. Features of this rule are: distinction of the provisions of the rule from provisions of the essentiality of application, relativity of specificity, generality and generalization at the level of developmental commentary. This rule is not current in relation to "universal word and universal occasion" and "specific word and specific occasion" about which generalization is meaningless. Since generalization means generalization of decree and in narrating history in historical verses there is no decree, this rule would not be current in these types of verses, too. The backgrounds that made this rule to be allocated to commentary of Quran include: dominating mismatch of word and occasion in the Quran and maximum separation of text from context in the Quran.
