Hazrat Abdullah bin Sarjis (may Allah be pleased with him) once said about himself that I presented myself in the service of the Prophet (peace and blessings be upon him) and ate food with him. I said to him, "O Messenger of Allah, may Allah grant you forgiveness." The narrator says that I asked him, "Did the Prophet (peace and blessings be upon him) also seek forgiveness for you?" He said, "Yes, and he also did so for you." Then he recited this verse: "And seek forgiveness for your faults and for the believing men and women." Then I saw the Seal of Prophethood between his two shoulders, which was on the corner of the left shoulder and was like a fist. He made a fist and showed it by gesture, and on the Seal of Prophethood there were raised moles like warts.
