This version adds (to the previous hadith No 4194):

My father said to him (the Prophet): Show me what is on your back, for I am a physician. He (the Prophet) said: You are only a soother. Its physician is He Who has credit it.

حَدَّثَنَا مُحَمَّدُ بْنُ الْعَلاَءِ، حَدَّثَنَا ابْنُ إِدْرِيسَ، قَالَ سَمِعْتُ ابْنَ أَبْجَرَ، عَنْ إِيَادِ بْنِ لَقِيطٍ، عَنْ أَبِي رِمْثَةَ، فِي هَذَا الْخَبَرِ قَالَ فَقَالَ لَهُ أَبِي أَرِنِي هَذَا الَّذِي بِظَهْرِكَ فَإِنِّي رَجُلٌ طَبِيبٌ . قَالَ
" اللَّهُ الطَّبِيبُ بَلْ أَنْتَ رَجُلٌ رَفِيقٌ طَبِيبُهَا الَّذِي خَلَقَهَا " .
