الفرق، والنقض، والمعارضة
Material distinction, counterinstance, and opposing proof.
Farq: Showing a legally relevant difference between the original and new case.
Naqḍ: Presenting a counterinstance in which the alleged cause exists but the claimed ruling does not, thereby challenging the proposed generalization.
Muʿāraḍah: Advancing competing evidence or a cause with sufficient legal force to oppose the proposed inference.
All three require a legally meaningful connection to the original case, new case, or cause. A different example by itself is insufficient unless it supplies a material distinction, a counterinstance, or an opposing proof.
