I went to the Prophet peace be upon him, and with me was my son. I said to my son, when I saw him, "This is the Prophet of Allah." Then he (my son) had a seizure. So I said to the Prophet ﷺ, "O Prophet of Allah, I am a physician and my father was a physician from a family of physicians. Show me your back, if there is a lump on it, I will treat it, and if it is something else, I will inform you. For there is no one more knowledgeable than me regarding injuries and wounds." He said, "There is no physician except Allah, and upon him are two green bandages, and he has hair that has turned gray, and his beard is red." Then he said, "Is this your son?" I said, "Yes, I swear by the Lord of the Kāba." He said, "Is it from yourself?" I said, "I testify to it." He said, "Indeed, it does not harm you nor does it harm him."
أَتَيْتُ النَّبِيَّ ﷺ وَمَعِي ابْنِي فَقُلْتُ لِابْنِي لَمَّا رَأَيْتُهُ هَذَا نَبِيُّ اللهِ فَأَخَذَتْهُ الرِّعْدَةُ مِنْهُ فَقُلْتُ يَا نَبِيَّ اللهِ إِنِّي رَجُلٌ طَبِيبٌ وَكَانَ وَالِدِي طَبِيبًا مِنْ أَهْلِ بَيْتٍ أَطِبَّاءَ فَأَرِنِي ظَهْرَكَ فَإِنْ كَانَ سِلْعَةٌ أَبُطُّهَا وَإِنْ كَانَ غَيْرَ ذَلِكَ أَخْبَرْتُكَ فَإِنَّهُ لَيْسَ مِنْ إِنْسَانٍ أَعْلَمَ بِجُرْحٍ أَوْ جِرَاحٍ مِنِّي قَالَ لَا طَبِيبَ إِلَّا اللهُ وَعَلَيْهِ بُرْدَانِ أَخْضَرَانِ وَلَهُ شَعَرٌ قَدْ عَلَاهُ الشَّيْبُ وَشَيْبُهُ أَحْمَرُ فَقَالَ ابْنُكَ هَذَا قُلْتُ إِيْ وَرَبِّ الْكَعْبَةِ قَالَ مِنْ نَفْسِكَ قُلْتُ أَشْهَدُ بِهِ قَالَ أَمَا إِنَّهُ لَا يَجْنِي عَلَيْكَ وَلَا تَجْنِي عَلَيْهِ
