وَمَنْ طَافَ طَوَافَ الْقُدُومِ مُحْدِثًا: فَعَلَيْهِ صَدَقَةٌ، وَإِنْ طَافَ جُنُبًا: فَعَلَيْهِ شَاةٌ.
Translation: A person who performs arrival tawaf without wudu owes charity; one who performs it in major ritual impurity owes a sheep offering.
Muhdith here denotes someone lacking wudu; junub denotes major ritual impurity requiring ghusl. The latter is not merely another label for the former.
This clause governs arrival tawaf, not the principal Hajj tawaf.
