«إذا اجتمع السبب مع العلة يضاف الحكم إلى العلة دون السبب»
Where sabab and illah occur together, the ruling is attributed to the illah rather than merely to the sabab.
The text gives the example of a person who steals someone else’s property and then destroys it. Theft may be the route leading to destruction, but liability for the loss is connected to destruction itself.
The rule teaches attribution: determine the legally operative factor rather than assigning the ruling to whichever event happened first.
