Is there a specific supplication when visiting the Prophet (peace and blessings be upon him)?

Question:
May Allah reward you with good, and may He do you good. Is there a specific supplication when visiting the Prophet (peace and blessings be upon him)?

Answer:
Visiting the grave of the Prophet (peace and blessings be upon him) is like visiting any other grave. It is prescribed, when greeting the Prophet (peace and blessings be upon him) and his two companions Abu Bakr and 'Umar (may Allah be pleased with them), to stand facing the Prophet (peace and blessings be upon him) and say: "Peace be upon you, O Messenger of Allah, and the mercy of Allah and His blessings." If one adds to this, he may say: "I bear witness, I bear witness that you have conveyed the message, fulfilled the trust, advised the community, and striven in the cause of Allah with true striving, and may Allah reward you with the best reward for a Prophet toward his people." There is no harm in this, for this is among his attributes (peace and blessings be upon him). Then he moves back to his right, toward the east, the length of an arm, and greets Abu Bakr al-Siddiq. He stands facing the grave and says: "Peace be upon you, O Abu Bakr al-Siddiq, and the mercy of Allah and His blessings." Then he moves back the same distance toward the east and says: "Peace be upon you, O 'Umar, O Commander of the Faithful, 'Umar ibn al-Khattab, the mercy of Allah and His blessings." Then he departs. This is the greeting of the Prophet (peace and blessings be upon him) and his two companions. This is done with a lowered voice and with proper conduct. It is not permissible to make supplication at the grave of the Prophet (peace and blessings be upon him). If he wishes to make supplication, he departs and makes it in the Prophet's Mosque. Yes?
