«طرفا الشرطية - أعني المقدم والتالي - لا حكم فيهما حين كونهما طرفين»
The two sides of a conditional, namely its antecedent and consequent, are not independently judged while they function as its two components.
This does not make those clauses meaningless or intrinsically incapable of forming assertions. The judgment made by the whole conditional concerns the specified relation between the sides; it does not necessarily assert each side as an actual fact.
“If it rains, the road will be wet” does not by itself assert that it is raining now or that the road is presently wet.
