وَمَنْ لَبِسَ الْجُرْمُوقَ فَوْقَ الْخُفِّ: مَسَحَ عَلَيْهِ.
Meaning: One who wears an outer jurmūq over a khuff may wipe over the outer layer.
A jurmūq is an outer overboot worn over the khuff. When the original conditions of khuff-wiping remain satisfied and the outer item meets the required characteristics, wiping its outer surface is permitted.
This does not extend the rule indiscriminately to every loose cloth covering.
