Is visiting the tomb of the Prophet (PBUH), Al-Baqi', Uhud, and Quba' obligatory for pilgrims, both men and women, or for men only?

Pilgrims are not obligated to visit the grave of the Prophet (peace be upon him) or Al-Baqi'. Rather, it is absolutely forbidden to undertake a journey specifically to visit graves. It is also forbidden for women to visit graves, even without undertaking a journey, due to the Prophet's (peace be upon him) saying: "(Do not undertake a journey) to visit any mosque except three: this mosque of mine (in Medina), the Sacred Mosque (in Mecca), and Al-Aqsa Mosque (in Jerusalem)," and because the Prophet (peace be upon him) cursed women who visit graves. It is sufficient for women to pray in the Prophet's Mosque and to frequently send blessings upon the Prophet (peace be upon him).
