«إِلَى الْمَرَافِقِ»
“Up to the elbows.”
The elbows are named as the limit in the command to wash the arms. Their inclusion is not based on a blanket rule that ila always includes its endpoint; the analysis concerns how the command delimits the body part to be washed.
In Hanafi jurisprudence, the elbows are included in the required washing. This is explained through the type of delimitation that ila produces in this context.
