وَمَنْ طَافَ طَوَافَ الصَّدْرِ مُحْدِثًا: فَعَلَيْهِ صَدَقَةٌ، وَإِنْ طَافَ جُنُبًا: فَعَلَيْهِ شَاةٌ.
Translation: Whoever performs farewell tawaf without wudu owes charity; whoever performs it in major ritual impurity owes a sheep.
Tawaf al-sadr is another name for farewell tawaf. Lack of wudu incurs charity; major impurity incurs a sheep.
The same defects have higher penalties in the principal Hajj tawaf. Do not generalize one tawaf’s penalty to every other tawaf.
