Sayyiduna Jabir bin Samurah (may Allah be pleased with him) narrates: I came towards the Prophet (peace and blessings be upon him) from behind, in order to look at the place of the Seal of Prophethood. When he (peace and blessings be upon him) looked at me, he removed his cloak, and I beheld it. (Allamah al-Haythami says:) I say: A hadith from this Companion about the Seal of Prophethood is mentioned in the "Sahih", other than this report.
Imam al-Tabarani recorded it, and its chain contains a narrator whom I do not know.
