Visiting the shrine of one of the friends of Allah signifies goodness and blessing.
Seeing the shrine of one of the prophets signifies goodness, blessing, and the intercession of that prophet. Visiting the shrine of Moses, peace be upon him, signifies being among the people of Paradise. Likewise, visiting the grave of Abraham, peace be upon him, signifies goodness and blessing, generosity and liberality, spending wealth in the path of Allah, and righteousness in religion. Visiting the blessed grave of the Noble Prophet in Medina signifies going on pilgrimage, the Prophet's intercession, and migration in the path of Allah.
