Pilgrimage is a practical expression of Tawheed .

This is what the pilgrim announces at the beginning of his Hajj, as Djabir ibn Abd-Allah says in his description of the pilgrimage of the Prophet (peace and blessings of Allaah be upon him ): "He (the Prophet) proclaimed the tawhid  :  Labbayka lahbayka Labbayka la sharika laka Labbayka Inna al-hamda wa an-ni'mata lakawal moulk Laa Sharika laka. ".

 The Hajj makes it possible to remember the afterlife when all the pilgrims gather on the esplanade of Arafat and elsewhere in the same state and without any distinction. Here all the differences disappear and no one is superior to another except by piety.

The Hajj symbolizes the unity of the Muslims because the pilgrims are equal in their dress, in the rites they observe. They all face the same qibla (direction of La Kaaba) and head towards the best places. No one is superior to another, neither ruler, nor governed, nor rich, nor poor, neither black nor white. Here the pilgrims are equal in rights and duties: "  they are all of Adam and this is from the earth. Arabic is not superior to the non-Arab, nor the white to the black, except by piety. "As claimed by our Prophet (peace and blessings of Allah be upon him) on his farewell pilgrimage.

 The Hajj allows people to be educated so that they are content with the strict minimum of clothing, accommodation and food. The pilgrim's dress is made up of two simple pieces of fabric and his bed is reduced to a place that just allows him to sleep.
