والصحيح من المذهب: أن موجبه الوجوب إلا إذا قام الدليل على خلافه.
The adopted position is that the unqualified command entails obligation unless evidence indicates otherwise.
This rule has two parts. First, obligation is the default when the Lawgiver commands an action without qualification. Second, a valid indication can alter the legal grade. An apparent command expressing permission, for instance, cannot be treated in isolation from the context that makes it permissive.
The principle therefore does not mean that every imperative in every situation is invariably obligatory. Its method is to begin with obligation for an unrestricted authoritative command, then consider whether proof diverts it toward another ruling.
Both the default and its qualification are essential to the rule.
