Comparison of the Ash'ari and Mulla Sadra Views in the rule that Says "There is No Effect on the Existence Except Allah"

The rule "There is No Effect on the Existence Except Allah" is emphasized by the Ash'arites and Mulla Sadra. But each has offered a different interpretation of this rule; According to this rule, the Ash'arites have denied any causation, influence, or effect among the possibilities, and attribute all actions exclusively and directly to God Almighty. But Mulla Sadra, based on his philosophical principles in transcendent wisdom, while proving the near activity of God for all actions, also accepts a role for other possibilities in actions and proves a kind of influence and effect among the obligatory sub-transcendence. In this article, with a descriptive-analytical-critical method, both views in this regard were examined. Accordingly, neither view is flawed. Of course, Mulla Sadra's view, with the explanation given by Mullah Ali Modarres, is largely free from problems.
