abudawud:4587Muḥammad b. al-ʿAlāʾ > Ḥafṣ > ʿAbd al-ʿAzīz b. ʿUmar b. ʿAbd al-ʿAzīz > Baʿḍ al-Wafd al--Adhīn Qadimūā from my father

Some people of the deputation which came to my father reported the Messenger of Allah ﷺ as saying: Any physician who practises medicine when he was not known as a practitioner before that and he harms (the patients) he will be held responsible. AbdulAziz said: Here physician does not refer to a man by qualification. it means opening a vein, incision and cauterisation.  

أبو داود:٤٥٨٧حَدَّثَنَا مُحَمَّدُ بْنُ الْعَلاَءِ حَدَّثَنَا حَفْصٌ حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ عُمَرَ بْنِ عَبْدِ الْعَزِيزِ

حَدَّثَنِي بَعْضُ الْوَفْدِ الَّذِينَ قَدِمُوا عَلَى أَبِي قَالَ قَالَ رَسُولُ اللَّهِ ﷺ أَيُّمَا طَبِيبٍ تَطَبَّبَ عَلَى قَوْمٍ لاَ يُعْرَفُ لَهُ تَطَبُّبٌ قَبْلَ ذَلِكَ فَأَعْنَتَ فَهُوَ ضَامِنٌ قَالَ عَبْدُ الْعَزِيزِ أَمَا إِنَّهُ لَيْسَ بِالنَّعْتِ إِنَّمَا هُوَ قَطْعُ الْعُرُوقِ وَالْبَطُّ وَالْكَىُّ
