When discussing the companions of Imam Hussain (AS), the most significant aspect to consider is their actions and decisions in specific circumstances where they had to make choices. While reading history, it might seem ordinary to us that when faced with oppression and injustice, any rational human being would stand against it. However, before making decisions, people need to be sure if their resistance is worthwhile.

Throughout history, many people fought and died for what they believed to be the truth, only to find out they were supporting evil.

In this text, we will delve into some of the most astonishing characteristics of the companions of Imam Hussain (AS) that made them so special in history.

Obedience

The outcome of faith is guidance: 

“Whoever has faith in Allah, He guides his heart.” (64: 11) 

However, this guidance is achievable through obedience: 

“O you who have faith! Obey Allah and obey the Apostle and those vested with authority among you.” (4: 59)

The most vital trait of the companions of Imam Hussain (AS) was their faith and reliance on Allah, and their obedience to Him, His messenger, and their leader - Imam Hussain (AS). 

On the night of Ashura, Imam Hussain (AS) gathered his companions and said “I release you from the allegiance and oath you’ve taken from me. The darkness of the night surrounds you, so break free from the turmoil hidden in the darkness waves. Then each of you may hold of the hand of my family members and disperse into the villages and cities until Allah grants you relief .” The companions, one by one, replied “By Allah! We shall not abandon you. In fact, we are ready to sacrifice our lives for yours. We shall defend you with our necks, faces and hands. We will fulfill our duty even if it costs our lives.” [1]

Distinguishing right from wrong

The situation in the year 61 AH during the battle of Karbala was perplexing. People had to differentiate between the truth among two groups both claiming to fight for Islam. Imam Hussain (AS) left Medina as he knew Yazid, the son and the successor of the late caliph, disregarded Islamic principles. However, since Yazid and his ministers presented themselves with an Islamic facade, it was challenging for ordinary people to discern the correct side. Consequently, most Muslims were deceived by their hypocritical behavior, or they were threatened by Yazid’s ministers due to fears of losing material gains, causing them to join Yazid’s army. 

It this context, Yazid managed to amass of over thirty thousand soldiers, while only few individuals - less than a hundred – chose to stand with Imam Hussain (AS). This fact highlights the great wisdom and bravery of Imam Hussain’s (AS) companions, and this wisdom, as the Quran mentioned, arises from steadfast faith:

“O you who have faith! If you are wary of Allah, He shall appoint a criterion for you, and absolve you of your misdeeds...” (8:29)

The Arabic term translated as “criterion” in the above verse is Furqan. Furqan is the power to distinguish right from wrong, a type of wisdom and insight bestowed by Allah upon His pious servants, which is not dependent on knowledge, literacy, or information. [1]

Based on this criterion granted by Almighty Allah, the companions of Imam Hussain (AS), coming from diverse ages and social, cultural and religious backgrounds, were all able to differentiate between right from wrong. It is regrettable that only a few comprehend this distinction! 
“… But most of them do not know the truth, and so they are disregardful.” (21: 24)

Detachment from the world

Even among the faithful, some chose not to oppose Imam Hussain (AS) in the battle of Karbala. They remained silent and withheld their support for the Imam. The status of these believers differs from those who sacrificed their possessions and lives for the sake of Allah (SWT). Allah says in the

Quran: 

“Not equal are those of the faithful who sit back—excepting those who suffer from some disability—and those who wage jihad in the way of Allah with their possession and their persons. Allah has graced those who wage jihad with their possessions and their persons by a degree over those who sit back…” (4: 95)

Loving Allah (SWT) and Being Loved by Allah (SWT)

Allah describes the relationship between Him and His pious servants as a mutual bond of love, with Allah (SWT) being the first to express love. In a beautiful Quranic verse Allah portrays His faithful, courageous, and humble servants as individuals loved by Him: 

“O you who have faith! Should any of you desert his religion, Allah will soon bring a people whom He loves and who love Him, [who will be] humble towards the faithful, stern towards the faithless, waging jihad in the way of Allah, not fearing the blame of any blamer. That is Allah’s grace, which He grants to whomever He wishes, and Allah is all-bounteous, all-knowing.” (5: 54)

This verse underscores that these individuals may face criticism and blame from due to their decisions, but it will not make them turn away from their spiritual path. 

Sacrifice

Another important characteristic of Imam Hussain’s (AS) companions was their selfless sacrifice in upholding the religion and tradition of the Prophet (PBUH&HP). It takes a noble soul to make sacrifices for others, and even more so when sacrificing one’s life to preserve the religion of Allah (SWT). This is why in the loving relationship that the companions of Imam had with their Lord, they presented their body and soul in defending the truth. 

“And among the people is he who sells his soul seeking the pleasure of Allah, and Allah is most kind to [His] servants.” (2:207)

Making pilgrimage to Karbala, where Imam Hussain (AS) and his loyal companions were bravely martyred, takes one of the highest places in a Shia’s wish list. All around the year, Karbala hosts the pilgrims who want to visit the holy shrine of Imam Hussain (AS). But the pilgrimage in Arbaeen is different.

“Arbaeen” takes place forty days later than “Ashura”. “Arbaeen pilgrimage” is actually one of the largest annual public gathering in the whole world. Millions of Shias and Sunnis or even many Christians, Yazidis and other faiths with various nationalities participate in this grand religious ceremony and gather from all around the world in the city of Karbala. A remarkable number of them takes this trip on foot and walks from Najaf to Karbala (approximately 80 kilometers). 

Many Muslims try so hard to make it to Karbala on Arbaeen and many Iraqis do their best to serve the pilgrims. During these days, copious amount of food, water, as well as small medical facilities which is run by GPs and specialists, and tents for resting are available along the route and in the cities where the pilgrims stay and visit. These services are all provided free by the native people.
Considering this large number of pilgrims and the great amount of money and time that is spent for this pilgrimage, this question may pop into many minds: What is it for?

Many goals and reasons can be mentioned for why we _Shias_ take this trip and go to the Karbala. In this text, we mention one of these reasons which is of great importance.  
Among the many goals of the “Arbaeen walk” ceremony, introducing Imam Hussain (AS) to the whole world seems to be the most significant one. The public gathering of Arbaeen gives us a precious opportunity to make people get to know Imam Hussain’s personality (AS) and understand his message. This unprecedented and unique event that happens only once a year can be so attractive for people around the world who yearn for finding the truth. 

Arbaeen walk is an Exhibition

Arbaeen ceremony is a unique event in which people and society go through a huge change, which isn’t seen in any other part of the world. Millions of people gathering in three or four Iraqi cities in about twelve days just for visiting the holy shrines can be a disaster to any other similar countries, but Iraqi people host this ceremony without any difficulties. In these days unlike other times, money loses its meaning. For maintaining peace and discipline, people themselves are enough and there’s not much need for police forces. People won’t be hungry, homeless or harmed by any person. In these days, people are even braver compared to other days, because they dare to face many problems and dangers that are otherwise intolerable. Even when the ISIS was in Iraq threatening the pilgrims, millions of people participated in this ceremony (1).
In this regard Imam Sadiq (AS) says: 
O God! Our enemies frowned on their journey and threatened them, but it didn’t stop our followers from getting up and departing towards us in spite of the enemy’s opinion (2). 
When people around the world observe this great exhibition, they understand the truth about Islam and Shi’ism which the terrorists like ISIS tried to taint. 

Furthermore, Arbaeen walk offers the whole humanity a glimpse at Islam’s suggested life style and civilized society: A society with no war, no poverty, hunger, and no discrimination. 

The sound of Imam Mahdi (AS)

As said before, introducing Imam Hussain (AS) is the most significant objective of this grand ceremony. The importance of this purpose lies in the fact that introducing Imam Hussain (AS) and his message is actually introducing our only awaited Imam, Imam Mahdi (As) to the whole humanity. By telling people who is Imam Hussain (AS), we are actually making people familiar with the Shia Imams and the massage of this faith. Shias believe their Imams are all like each other and they seek one goal, which is spreading the peaceful message of Islam to the whole world. This is actually the essential message of Islam, too. The Holy Quran says:
It is He who has sent His Messenger with guidance and the true religion, that He may make it prevail over all religions, and Allah suffices as witness (48:28)
Certainly We sent Our messengers with manifest proofs, and We sent down with them the Book and the Balance, so that mankind may maintain justice (57:25)
Imam Mahdi (AS) is the last Imam who is destined to carry out this mission and we, as his followers, are obliged to raise awareness about His mission and himself. When people understand the message of Imam Hussain (AS) they actually understand Imam Mahdi’s message (AS) since there is no difference between them. The Holy Prophet (PBUH & HP) says:
Allah almighty created me and my Household [the twelve Imams] from one same light (3)Imam Sadiq (AS) also says:
There is always a justful successor among us who defend the religion against the falsification of the extremists, plagiarism of the disbelievers and the wrong understanding of the fools. (4)   
According to the prophecies about the last Imam (AS) when he arrives and introduces himself to the people, all the world hears his voice in their language at the same time. Then, Imam Mahdi (AS) introduces himself as the descendant of Imam Hussain (AS):
O people of the world! Indeed my grand ancestor Hussain (AS) was killed while he was thirsty, O people of the world! Indeed he was left on the earth with no cloth, O people of the world! Indeed he was beaten so hard out of animosity (5)

Clearly, when people hear this voice, must know who is Hussain (AS); so, it’s our duty to make them familiar with him.
