Abu Ramtha reported,

I went out with my father when I was a young boy, and we came to a man who was sitting in the shade of his house at midday. He was wearing two green garments, his hair was thick and full, and on his head was a trace of henna.My father said to me, "Do you know who this is?"I said, "No."He said, "This is the Messenger of Allah ﷺ."We then talked for a long time. My father said to him, "I am a man from a family of medicine. Show me what is on your back between your shoulders. If it is a tumor, I will remove it for you, and if it is something else, I will tell you what it is."The Messenger of Allah ﷺ replied, "Its physician is the One who created it."Then the Messenger of Allah ﷺ looked at me and said to him, "Is this your son?"He said, "I bear witness that he is."The Messenger of Allah ﷺ said to him, "Consider what you say."He said, "Yes, by the Lord of the Kaabah."The Messenger of Allah ﷺ then laughed at my resemblance to my father and at my father's swearing concerning me, and he said, "This one, he will not bring guilt upon you, nor will you bring guilt upon him."

حدثنا عبد الله حدثنا محمد بن بكار حدثنا قيس بن الربيع الأسدي عن إياد بن لقيط

عن أبي رمثة قال

انطلقت مع أبي وأنا غلام فأتينا رجلا من الهاجرة جالسا في ظل بيته وعليه بردان أخضران وشعره وفرة وبرأسه ردع من حناء قال فقال لي أبي أتدري من هذا فقلت لا قال هذا رسول الله ﷺ قال فتحدثنا طويلا قال فقال له أبي إني رجل من أهل بيت طب فأرني الذي بباطن كتفك فإن تك سلعة قطعتها وإن تك غير ذلك أخبرتك قال طبيبها الذي خلقها قال ثم نظر رسول الله ﷺ إلي فقال له ابنك هذا قال أشهد به فقال له رسول الله ﷺ انظر ما تقول قال إي ورب الكعبة قال فضحك رسول الله ﷺ لشبهي بأبي ولحلف أبي علي فقال رسول الله ﷺ يا هذا لا يجني عليك ولا تجني عليه
