Faa cannot be interpreted by ignoring the type of legal sentence in which it appears.
Example 1: “جاء زيد فعمرو” — succession in time.
Example 2: “إن دخلت الدار فأنت طالق” — a conditional consequence.
Example 3: “أبشر فقد أتاك الغوث” — an explanatory reason.
All three connect the following part to what precedes it, but the kind of connection differs. Legal interpretation must identify whether a condition, acceptance, permission, or reason is actually involved, rather than treating every faa as identical.
