«فالسبب: ما يوصل إلى الشيء من غير تأثير فيه»
A sabab is something that leads to another thing without itself exerting the relevant effect.
The author compares a road leading to a destination and a rope through which water is reached. Neither creates the destination or the water.
Likewise, in legal reasoning a sabab can be connected to a ruling without necessarily being its effective cause. The two terms must not be equated without examining the author’s intended use.
