وذلك نوعان: أحدهما ما إذا كان منشأ الخلاف في الفصلين واحدًا.
The first form occurs when the two disputes arise from one common underlying issue.
والثاني: ما إذا كان منشؤه مختلفًا، والأول حجة والثاني ليس بحجة.
The second occurs when their underlying grounds differ; the first is authoritative, the second is not.
One origin: both cases follow a shared legal principle, so establishing that principle affects both.
Different origins: cases may look related but have separate proofs. Resolving one does not automatically resolve the other.
