وَعَنْ عَمْرِو بْنِ شُعَيْبٍ عَنْ أَبِيهِ عَنْ جَدِّهِ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «من تطيب وَلَمْ يُعْلَمْ مِنْهُ طِبٌّ فَهُوَ ضَامِنٌ» . رَوَاهُ أَبُو دَاوُد وَالنَّسَائِيّ

‘Amr b. Shu'aib, on his father’s authority, said his grandfather reported God’s Messenger as saying, “Anyone who practices medicine when he is not known as a practitioner will be held responsible.”* Abu Dawud and Nasa’i transmitted it. *He will have to pay blood wit if the patient dies.
