Unity between Muslims is considered as a crucial matter in Islam. Thus, the Quran compares discordance and disunity among Muslims to “a pit of the Fire”: "And hold firmly to the rope of Allah all together and do not become divided...And you were on the edge of a pit of the Fire, and He saved you from it." (3:103). Looking at the former nations, we find them honored and glorious when they were united, but disgraced and vulnerable when they fell apart [3]. Hajj, as one of the obligatory rituals in Islam, is one of the ways which encourages unity among Muslim nations. Let’s see how.

 Every Muslim is Welcomed to Hajj, No Exception!

There is no other ritual, social, or political program in Islam greater than Hajj, where every Muslim from any corner of the world finds the chance to approach others and communicate with them freely. 
Besides, it provides the opportunity to strengthen the emotional, social, and religious bonds with other Muslims. Hajj is a social kind of worship that represents the glorious Islamic unity through its numerous participants of various nationalities, skin colors, languages, and sects who are like brothers (49:10). They have left behind the religious conflicts, and follow the same intention, perform the same actions, and wear the same outfit.   

Hajj Brings Muslims Power

In Surah Ma’idah, it is stated that coming together around Ka’aba makes Muslims powerful (5:97). In other words, the aim of Hajj for Muslims is not just performing some physical actions. It is to bring Muslims of different races and origins together to get acquainted, communicate with each other, initiate political, economic and cultural relations, and find themselves closer to each other despite their many differences. 

Besides, Islam calls “every” Muslim to Hajj, which means that everyone, regardless of origin and skin color, is invited to the land of Allah. It reminds us of what the Quran says; that there is no superiority except rightfulness and the most righteous, is the noblest in the sight of Allah (49:13). This is an important message, especially for the less powerful Islamic nations, causing them to feel more confident and encouraging them to communicate with other Muslims, which ultimately results in a more united Muslim society. 

Muslims Are Like the Hands which Help Each other

In a discourse that Prophet Muhammad (PBUH&HP) has given during one of his Hajj pilgrimages, he described Muslims as brothers, and like a single hand (a united community) when facing the enemies [2]. Emphasizing brotherhood among Muslims during Hajj shows that this ritual was a good representation of unity. Thus, Muslims are expected to support each other and be close to each other as they are during Hajj.

Two Axes of Solidarity in Hajj

During Hajj, Muslims learn and practice solidarity in two main areas:

1. Ideology and Principles

During Hajj, Muslims can exchange ideas with Muslims of other sects. In the early years of Islam when non-Muslims also went to Mecca for their religious rituals, Prophet Muhammad (PBUH&HP) took this opportunity to introduce Islam to them and exchange ideas with them to spread his message and find followers in other cities, too. In Hajj, many misunderstandings and ideological conflicts can be discussed among Muslims, and the real beliefs of different sects about the others can be clarified. Hence, the wrong prejudgments and hostilities can be rectified. According to Imam Sadiq (AS), Hajj is a means to gather all Muslims from east to west to let them get acquainted with each other and achieve consensus [3]. 

2. Social and Political Matters

Through the communications that Muslims have during Hajj, they find out the social achievements and national advances in other Muslim nations and might decide to follow their path. They also learn about the social problems and deficiencies of others and might find solutions by further cooperation. Moreover, they become aware of the real political situations of other Muslim countries, especially the difficulties that sometimes other countries impose on them. For instance, one of the goals of Hajj is to announce the support of Muslims for Palestinians and those oppressed in the world. This helps Muslims to become more united against common enemies of Islam.

To summarize, Hajj is a time that a Muslim finds him/herself in the accompaniment of millions of others who wear as simple as him/her and who repeat the same words as him/her as they move around Ka’aba. This is where “one” is transformed into the totality of ‘people’, establishing the universality of the Islamic community with the goal of approaching Allah.

After introducing the axioms of Islam and finding faith in them, the next step in this life-changing journey is to accomplish certain commands as a result of those beliefs which will lead us to a life of eternal satisfaction and bliss. Now one might wonder, what relates those fundamental principles or axioms – i.e., Monotheism (Tawhid) [1], Prophethood (Nubuwwah), and Afterlife (Ma’ad) – to practical principles in Islam? Are they even related? If yes, how is this relationship justified? What comes next will hopefully provide an answer to these questions.  

What is religion?

To have a better understanding of the relationship between the axioms and practical principles in Islam, we should first fully grasp the meaning of religion. Religion, in one sense, is defined as the collection of a series of fundamental and necessary beliefs -axioms- along with some practical commandments. The beliefs are the foundations, and the instructions are the means of putting the axioms into practice that may include juridical, legal, social, ethical, spiritual, and political rules and regulations.

The Elements of Religion

Having the definition of religion in mind, we can consider two elements or constituent parts for it: 1. Beliefs (axioms), 2. The practical commandments and instructions (practical principles). Typically, since the instructions are devised with regard to the axioms, then these principal beliefs are considered as primary, a prior, and foundational, while the practical commands become subsidiary, ancillary, and as the pillars built on those foundations.

In addition, according to the Islamic doctrine, the prerequisite of this religion is one’s faith in the existence and Oneness of God as well as in the Prophethood of Muhammad (PBUH&HP) and the coming of the Judgment Day; that no one deserves worshiping other than Allah Almighty, Prophet Muhammad (PBUH&HP) has been chosen for Prophethood by Him as the last prophet and that this life is surely followed by another one.  

The first two are, as a matter of fact, the content of what we call Shahadatain or the two testimonies, that by uttering them, one will enter the world of Muslims. But, this is only a gateway to Islam and a platform for further practices that will ultimately make one a perfect Muslim and believer.

The Nature of the Relationship between the Elements of Religion

We might suppose many kinds of relationship between the elements - Axioms and Practical principles - of religion, including the pearl and shell relationship, the innate and parallel relationship, the root and stem relationship.

One case scenario is to consider the relationship between these two constituent parts like a pearl and its shell; that is one of these parts is primary, and the other secondary, and what matters is the primary one. In other words, it is enough for one to find faith in the axioms of religion and the practical principles are only there for us to reach those axioms; that being done, they have fulfilled their purpose, and there is no need for them anymore.

Analogously, the shell does not worth anything by itself; its only importance is to keep the pearl safe. Anyone who looks for a shell is actually after the pearl in it, and once he finds it, he will throw away the shell instantly.

Another case scenario regards this relationship of parallel and innate kind. It claims that religion has three aspects: Islamic law, the path, and truth. The axioms of religion are its truth, while the law and path - which are the practical principles of religion -   only provide the way to reach the truth. Thus, like the previous assumption, if someone reaches the truth, then he will no more need the law and the path. 

But what is the most proper relationship between these two? This association is neither like pearl and shell nor of parallel and innate kind. While we believe in the primacy of the axioms, we don’t consider the practical principles of religion as marginal and unimportant; there is a mutual relationship between practical doctrines of Islam and theoretical knowledge of religion.

If there is any suitable way of elucidating this issue metaphorically, that would be through the relationship of the root and stem of a tree. In this kind of relationship, no part can be considered as independent of the other, they closely correlate. Believing in certain axioms necessitates the manifestation of a particular demeanor which requires the reinforcement of the belief in those fundamental principles. Similarly, every root has its own kind of stem and fruit that will grow and be nourished by the sun and ultimately fortify the root.

The Difference between Axioms and Practical Principles in Islam

From what we have said so far, it is crystal clear that practical principles require active practice whereas axioms need knowledge and firm belief. Accordingly, in the case of the axioms imitation – no matter from who - is absolutely forbidden and they should be accepted through careful investigation and precise reasoning individually, while practical principles are mainly practiced with a degree of submission to God; the main purpose of these rules is the action itself.

That is why it is said that knowing and understanding the axioms is an “individual duty” – i.e. the duty that every single Muslim is bound to perform, e.g., performing Salat - for each Muslim, while being familiar with the practical principles is a “sufficiency [2] duty” – i.e., the duty that will lose its obligation if a group of Muslims has performed it.   

It is noteworthy that the actions and behaviors that practical principles suggest will not result in our spiritual and psychological revolution and development unless we have a thorough understanding of the axioms and have accepted them rationally. In other words, the religion is constituted of certain principles which are its intellectual basis and requires its followers to exhibit specific behaviors; these actions root back in those axioms, and the axioms are prior to them.

What are the Practical Principles?

Let’s have a brief look at the ten practical principles of the religion of Islam:  

Prayer (Salat): The performance of the daily prayer five times a day with a specific form.

Fasting (Sawm): The act of voluntarily preventing oneself from eating and drinking during a particular part of the day – from the time of Dawn Prayer (Salat al-Fajr) until Dusk prayer(Salat al-Maghrib).

The Holy Pilgrimage (Hajj):  An annual Islamic pilgrimage to Mecca, and a mandatory religious duty for Muslims that must be carried out at least once in their lifetime by those who are physically and financially capable of undertaking the journey, and can support their family during their absence.

Alms-tax (Zakat): Paying an exact amount of money that has become obligatory through the rules of Sharia in order to be used in favor of the people in need or for certain beneficial deeds in society.

Khums: A money proportional to one fifth that every person should pay based on some certain criteria.

The Holy Struggle (Jihad): Technically, a special kind of attempt, which includes sacrificing one’s life and property primarily for the sake of Allah, elevating and sustaining Islamic beliefs and standpoints. In this sense, Jihad is the act of Defending the Islamic territory against the assaults and intrusions of outsiders and invaders. Literally, this word is defined as the striving of one’s soul against the temptation of the devil and his own whim.   

Enjoining what is right (al-Amr bi-l-maʿrūf): To invite other Muslims to goodness and righteousness, with regard to certain conditions and through specific manners.

Forbidding what is wrong (nahy ʿani-l-munkar): To dissuade other Muslims from doing what is wrong, sinful or immoral, with regard to certain conditions and through specific manners.

Expressing Love towards Good (Tawalla): To have a feeling of affection and love, affirmation, submission, and acceptance toward guardianship of Allah, Prophet Muhammad (PBUH&HP), and the twelve Imams.

Expressing disassociation from Evil (Tabarra): having a feeling of disassociation and dislike toward the enemies of Allah, Prophet Muhammad (PBUH&HP) and twelve Imams.
