When you meet specific wording, check four things:
• Defined subject: a person, type, category or number.
• Scope: it does not include every member merely because the category can contain many members.
• Indication: its fixed meaning is decisive in the source framework unless valid evidence opens another possibility.
• Limit of use: preserve the exact fixed meaning and any condition attached by the source.
Khas begins with precise wording. It does not give permission to extend an example beyond the words and conditions actually taught.
