What is the ruling on women visiting graves, and is their visit to the grave of the Prophet, peace and blessings be upon him, an exception to this?

Visiting graves for women is permissible if it is for admonition and reflection, provided that no forbidden acts are committed, such as raising one's voice in wailing or lamenting. The proof for its permissibility is the general statement of the Prophet, peace and blessings be upon him: "I had forbidden you from visiting graves, so visit them." There is no difference in this regard between the grave of the Prophet, peace and blessings be upon him, and others.
