It is narrated from Sayyiduna Jabir bin Samurah, may Allah be pleased with him, who says: I saw the Seal between the two shoulders of the Messenger of Allah, peace and blessings be upon him, which was in the form of a red lump, like the egg of a pigeon.

Sayyida Rumaysah (may Allah be pleased with her) says that I heard this from the Messenger of Allah (peace and blessings be upon him) at a time when I was so close to him that if I wished, I could have kissed the Seal of Prophethood which was between his two shoulders, and the statement was this: When Sa’d bin Mu’adh (may Allah be pleased with him) passed away, on that day the Messenger of Allah (peace and blessings be upon him) said:“At his death, the Throne of Allah, the Exalted, began to shake.”

Ibrahim bin Muhammad Ali bin Abi Talib narrates that Sayyiduna Ali (may Allah be pleased with him) used to describe the attributes/appearance of the Messenger of Allah (peace and blessings be upon him)... Then he narrated a long hadith in which he said that between the two shoulders of the Noble Prophet (peace and blessings be upon him) was the Seal of Prophethood; he (peace and blessings be upon him) was the Seal of the Prophets.
