The Messenger of Allah (may Allah's peace and blessings be upon him) once said to me: "Get near to me," and I did

The Messenger of Allah (may Allah's peace and blessings be upon him) asked Abu Zayd al-Ansāri to get near to him. When Abu Zayd did that, the Messenger of Allah (may Allah’s peace and blessings be upon him) asked him to put his hand underneath his shirt in order to massage his back. Abu Zayd,(may Allah be pleased with him) put his hand underneath the shirt of the Prophet (may Allah's peace and blessings be upon him) and massaged his back.

When he began massaging, his fingers accidentally touched the seal of prophet-hood. He was asked what the seal of prophet-hood was like and replied that it consisted of hair between the shoulders of the Prophet (may Allah’s peace and blessings be upon him).
