«حكمه: المطلق يجري على إطلاقه»
Its ruling is that an unrestricted expression operates according to its unrestricted sense.
One may not simply add an unstated condition to the term. If a ruling names an object without further qualification, a reader cannot supply an arbitrary new attribute.
If a request merely says “a book,” narrowing it to “a red book” changes the request. This does not mean that other independently established legal conditions can be ignored when analysing a full ruling.
