Visiting the holy shrine of the Holy Prophet ( Sallallahu alaihi wa sallam) is almost Wajib .

Translation of Hadith: The Messenger of Allah (Sallallahu alaihi wa sallam) said: Even after having the money for food and traveling, if any person does not perform Hajj, there is no difference between him and the Jews and the Christians .
And also said :
Translation of Hadith: Whoever dies without performing Hajj, even when there was no external reason or a threat from a cruel ruler or any kind of severe illness which did not allow that person to perform Hajj, then we don’t care whether that person dies as a Jew or a Christian .

Hadhrat Abu Jaa’far (May Allah shower His mercy on him) says :
Translation: Piety, which will stop a person from sinning, magnanimity, which will save that person from anger and being nice to one's friends, these are the signs of the Hajj being accepted .
After the Hajj, you interest in this material world should lessen and you should be more concerned about the hereafter .
The reward of an accepted Hajj (Hajj-E-Maqbool) is nothing but Jannah .
Hadhrat Imam Ghazali (May Allah shower His mercy on him) said: The journey of Hajj is similar to the journey of the hereafter. What is intended here is that by performing the articles, etc. of Hajj, and in the journey of the Hajj, the Hajjis are reminded of death and what happens after death .
For e.g., while leaving for the journey, while taking leave of the relatives, etc. the Hajji should think about the throes of death .
At the time of leaving the country, the Hajji should reflect upon leaving this world .
At the time of boarding any means of conveyance, the Hajji should think about his (or her) Janazah (i.e. when the dead body is being shouldered to the graveyard ).
At the time of wearing the white Ihraam, the Hajji should think about he (or she) being bound in the funeral shroud .
In the journey, while crossing the jungles and valleys, the Hajji should think about the difficult-to-cross valley, which one has to cross after death up to the Qiyamah, i.e. the Barzakh (the netherworld) i.e. the grave .
When facing difficulties in the journey, the Hajjis should think about the questions of Munkir and Nakeer and their helplessness .
At the time of the stay in the plane of Arafaat, all alone without the company of the relatives, friends, etc., the Hajji should think about the loneliness and terror of grave .
On facing difficulties due to insects, etc., the Hajji should think about the snakes and scorpions of the grave .
When saying "Allahumma Labbaik," one should think about the time when we are reawakened from death and come out of the grave, when you will come to the Mahshar when Allah Ta'ala gives the call .
