وَإِنْ حَلَقَ مَوَاضِعَ الْمَحَاجِمِ فَعَلَيْهِ دَمٌ عِنْدَ أَبِي حَنِيفَةَ، وَقَالَ أَبُو يُوسُفَ وَمُحَمَّدٌ: عَلَيْهِ صَدَقَةٌ
Translation: If he shaves the sites where cupping is performed, Abu Hanifah requires an animal offering, while Abu Yusuf and Muhammad require charity.
Mawadiʿ al-mahajim are the sites treated for cupping. The founders of the Hanafi school differ on this specific case, so it should not be presented as a wholly undisputed ruling.
Abu Hanifah states dam, while his two students state sadaqah. The passage is specific and should not be stretched to every medical grooming procedure without further legal analysis.
