It is stated in Hadeeth:
Whoever comes with the sole intention of visiting my grave, my intercession will become incumbent for that person.
Whoever visits my grave after my death is like the one who has visited me during my lifetime.
Recite Durood (salutations) in abundance on Rasulullah sallallahu alayhi wasallam, on  beginning your journey to and from Madinah Munawwarah, and during your stay there.

To hurt or cause inconvenience to any Muslim and especially the people of Madinah Munawwarah is a great sin.

Travel as a Lover Travelling to the Beloved
