«ما يكون الحكم في الفرع من نوع الحكم الثابت في الأصل»
An analogy in which the subsidiary ruling is of the same specific type as the established ruling.
The book uses a classical example involving marriage guardianship in two cases of minors. The claimed shared cause is minority and the legal effect is of the same type in each case.
The aim is to understand the analytical structure: a same-kind ruling is considered for a new case sharing the operative cause. The historical example does not independently settle contemporary legal requirements for marriage or guardianship.
