فَإِنْ خَرَجَ مِنْهُ شَيْءٌ غَسَلَهُ، وَلَا يُعِيدُ غُسْلَهُ
Translation: If any matter is discharged from the body, wash it off, but do not repeat the entire washing.
Ghasalahu means cleaning the discharge and affected area. Wa la yu‘idu ghuslahu explicitly rules out repeating the entire funeral bath. Local cleaning and restarting the full bath are distinct.
