The Seal of the Prophet Muhammad

Seal of the Prophets (Arabic: خاتم اﻟﻨﺒﻴﻴﻦ‎ Khātim an-Nabiyīn) is a title given to Muhammad by a verse in the Qur'an. [Qur'an 33:40] Muslims traditionally interpret this verse as meaning that Muhammad was the last prophet, although other interpretations exist.

HOWEVER hadith says this also ...

Sahih Muslim, Book 30 Book 30, Number 5793:

Abdullah b. Sarjis reported: I saw Allah's Apostle (may peace be upon him) and ate with him bread and meat, or he said Tharid (bread soaked in soup). I said to him: Did Allah's Apostle (may peace be upon him) 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.
