Is visiting the grave of the Prophet Muhammad (peace be upon him) forbidden for men and women, especially since the noble Hadith states: "Between my grave and my pulpit is a garden from the gardens of Paradise"?

Visiting the grave of the Prophet, peace and blessings be upon him, is not forbidden for men or women. Rather, it falls under the same ruling as visiting other graves, due to the Prophet's saying, "I had forbidden you from visiting graves, but now visit them, for they remind one of the Hereafter." The disagreement regarding women visiting graves is discussed in Fatwa no. 31789. The hadith mentioned in the question has no relation to the topic of visiting.
