Moley Molly

We are told that the founder of Islam had a protuberance on his back.

Abdullah b. Sarjis reported:

I saw Allah's Apostle (ﷺ) and ate with him bread and meat, or he said Tharid (bread soaked in soup). I said to him: Did Allah's Apostle (ﷺ) seek forgiveness for you? He said: Yes, and for you, and he then recited this verse:" Ask forgiveness for thy sin and for the believing men and believing women" (xlvii. 19). I then went after him and saw the Seal of Prophethood between his shoulders on the left side of his shoulder having spots on it like moles.

'Abdullah ibn Sarjis [al-MuzanI] said:

"I came to Allah’s Messenger (Allah bless him and give him peace), while he was among a group of his Companions, so I circled like this behind him. He understood what I wanted, so he threw the cloak off his back. I thus saw the place of the Seal on his shoulders, like a clenched fist surrounded by moles, as if they were warts. I came around to face him, and I said: 'May Allah forgive you, O Messenger of Allah!' He said: ‘And you,' so the people exclaimed: 'Allah’s Messenger (Allah bless him and give him peace) has asked forgiveness for you!' He said: 'Yes, and also for you!' Then he recited this Quranic verse: 'And ask forgiveness for your sin, and for the believing men and the believing women [was'tagh'fir li-dhanbika wa li’l mu'minina wal-mu’minat].”(Q.47:19).”’

Narrated Jabir bin Samurah:

"The seal of the Messenger of Allah (ﷺ)" - meaning the one which was between his two shoulder blades - "was fleshy and red, resembling the egg of a pigeon."

Now, it appears that a physician offered to remove it.

Abu Rimtha said:

I came to God’s Messenger with my father, and on his asking who this was along with him, he replied, “He is my son; be witness to the fact.” He said, “He will not bring evil on you, nor will you bring evil on him.”* Abu Dawud and Nasa’i transmitted it. * This is explained as meaning that neither will be punished for the wrong done by the other. In Sharh as-sunna there is an addition at the beginning. He said: I went in with my father to see God’s Messenger, and when my father saw what was on God's Messenger’s back he said, “Let me treat what is on your back, for I am a physician.” He replied, “You are the helper, but God is the Physician.”* *i.e. you act in a gentle manner giving help and advice, but only God can cure.

Did the founder of Islam initially see his protuberance as something that he might have been 'cured' of and later decided that it was 'the seal of prophethood'?
