Hajj, or pilgrimage to Mecca, the birthplace of prophet Mohammad and the City of prophet Ibrahim and the land of Adam when he recognized Allah and also the center of revelation of the Quran to mankind through his last messenger. The place of revelation of the law of the Creator, Quran, to all men at the House of people. It is mandatory for Muslims to perform this universal act of worshiping once in their lifetime. If one is able to do so. As it is mentioned in the Quran in Sura 3, Aya 97:

"And Men owe to Allah "pilgrimage to the House, those who can afford the journey…."

The laws of performing Hajj are mentioned in the Quran in ten places. Hajj or pilgrimage is performed in the month of Zul-Hajja or the twelfth month by all the Muslims regardless of their nationality or race. It presents unity and justice around the House of Allah, that is the House of the people according to His laws which are the laws for mankind. Hajj also means message. It is the message of how to activate our constitution, Quran, in action. The message of unity in uniformity of clothing (2 pieces of white material ) while in the boundary of the House and obedience to the law of the House. The message of one law in the House and around that law as one family together.

Arafat

Muslims are one. Their geographical differences are for their identity. In Islam our borders are open to each other. We live on the land of Allah. We are one Umma with different languages and race. No matter who we are, we recognize Allah as our means of sustenance on earth as Arafa means recognition of this fact.

Arafat is the name of the desert and day of Arafa is the ninth day of the month of Zul-Hajja, the day that everyone meets at this desert only to see each other, to live together a day to recognize each other as Arafa means to know - to be acquainted with Allah in being with each other. It is the place of every Muslim in the simple clothing of two pieces of white material. We know each other with the name of "Hajj" or one who is intending, not by title or rank. It is the land of equality, no boundary but different nations. No restriction of moving from one part to another. All the nations are brothers and are together in this vast desert. In the end of the day of Arafa, we all move to the valley of Muzdalifa or Mash'ar (awareness). If in the vast desert of Arafat we were separated and each group and nationality were by themselves, the valley of Mash'ar brings everyone together because we are in Mash'ar (awareness) . The night of Mash'ar is to pick up war materials (stones) so you can attack at dawn. We stay behind the boundary of Mina and pick up small stones or pebbles for each battle with Satan. You will need 7 stones for at least seven attacks on each evil or a total of 49 stones.

Hajj gives us a lesson of unity and togetherness and confrontation against evils and those who are against the unity of mankind. We can be united if we come together in Arafat (recognition) and reject evils in Mina and follow the law of Allah in Mecca as the rejection of any Deity is required to achieve Allah's will.
The reality we see is that Muslims are one "Ummah" and one nation with different languages and cultures and from different races and boundaries. In this desert, Muslims are neighbors to each other and spend a full day together as the World of Islam is one. We are not divided and the line of Allah is extended to hold firm on it and be not divided. The "Dzikr" and the words prayer chanted by different groups of races makes you of them. They may not speak your language but it shows and express clearly that the Quran is our constitution and the tradition of our beloved prophet is our way of life.

Mash-Ar

After 'recognition' in Arafat as we saw our unity in the light of day of Arafa, we then reach the night of Mash'ar. We have nothing to do but pick up stones (ammunition) to fight evil in the morning. The battle is with what is preventing us from being obedient to Allah and His command.
In the dark valley of Mash-Ar which is called Muzdalifa, your duty is to pick up pebbles for a battle to be performed at dawn, to attack the big evil, seven rocks for each attack and it must be your own rocks or fighting pebbles, not anyone elses. Make sure to take enough for seven attacks and some extra in case of missing the target during the attack.

Mina

On the dawn of the tenth day, the border of Mina will be broken and the big evil of "Jamaratul Owla" will be attacked. It is the day of battle and victory, the day of sacrifice where Ibrahim sacrifices his son. This is where we should sacrifice our Ismael, whatever our Ismael is , to achieve Allah's command.
Mina, the land of love where Ibrahim, Alaihes Salam, brought his beloved son Ismail to be sacrificed by the command of Allah. And now we as a family are moving to this area. The total surrender of Ismail cannot be explained any better than in the words of Allah in Sura 37, Aya 102:

"O my son, I have seen in a dream that I should sacrifice thee: so consider what you see. He said: O my father, do as you are commanded; if Allah pleases, you will find me patient."

Staying in Salat at the place of Ibrahim (Alaihes Salam). So follow the example of Ibrahim, the messenger of Allah, and his devotion in total submission to Allah. Yet strive in the humbleness of Hajer, the wife of Ibrahim and the Mother of Ismail. The way she moved and rushed from Safa and Marwa, one mountain to another in search of water for Ismail. And then upon completion of this act, give up some of your ownself, a part of your body (Taghseer) a piece of hair or a nail to be cut off from yourself as Ismail gave up his life and his total being for the cause and order of Allah. It was only a test.
By performing Salat at the place of Ibrahim we become the followers of the tradition of the prophets. It is our duty to help each other and to struggle to save lives as Hajer moves to save Ismail's life.
With the devotion of the son and submission of the father and the humbleness of the mother, a perfect examples of one Muslim family or one umma, what can prevent the march of Ibrahim and Ismail through Mina to the place of sacrifice. Man is continuously distracted from submission to Allah and man is equipped with the power of jihad against these obstacles.
When the dawn of the tenth day starts, the border of Mina will be broken and the aim is together, and all the nations, attack the big evil or Jamaratul-Owla and Allah's order in the Quran is the same as started in Sura 9, Aya 12:

"And fight the leaders of non-believers for their oaths are nothing to them that so they maybe restrained."

After the attack on the big evil (Jamaratul-Owla), we sacrifice the animal for the victory of the battle against the big evil.
The battle will be continued on the next day against 3 evils and the day after the same evils, as stated in Sura 8, Aya 39:

"And fight them until there is no persecution and religion is all for Allah."

You are continuously alert as long as you stay in Mina, as the smaller evils will become the leading evil. Therefore, the continuation of stoning the 3 evils will be done each day during your stay in Mina and as a Zul-Hajja, you may leave Mina to return to Mecca again, around the House of Allah, the gathering place of Umma.
This act is performed from Mecca to Arafat then to Mash'ar and to Mina and back again to Mecca, your House, the House of Allah with the same law that is for every move in every place for all mankind as long as we live.

"We come for Allah and to Him is our return."
