كما تقول لعين الماء: «هذه عين»
For a water spring one may say, “This is a ʿayn.”
“ʿAyn” can denote a spring or an eye; the commentary also discusses its use in relation to the sun. A predicate true of one meaning cannot be transferred to another solely because the expression is shared.
For example, “a spring releases water” and “an eye produces tears” involve different subjects and explanations. Their shared word does not make the predicates interchangeable.
