Imam Jawad (AS) is the ninth Shiite Imam. His father is Imam Reza (AS), and his mother’s name is  Sabikah. His original name is “Muhammad,” but his epithet is “Jawad,” meaning “a very generous person.” He was born on 195 H (810 AC) in Medina. (1)

Generally, Shiite Imams carried prestige among their tribe and were respected by everyone. Many Shias believed that Imams were merely knowledgeable people who gained their knowledge only from their ancestors and they were not extraordinary. However, the imamate of Imam Jawad (AS) made all the Shias think differently and change their minds. He was only eight years old, when his father, Imam Reza (AS), was martyred. According to hadiths, the earth cannot be without an Imam. Accordingly, Imam Reza (AS) said:
The earth cannot be without any of us, Imams, whether he is known by the people or hidden from them. (2)

Shias didn’t know who would be their leader after Imam Reza (AS). But, he introduced Imam Jawad (AS) as his successor (3) and showed the Shias that “Imam” was not an ordinary person and he could be the leader of the whole Shias despite being young. 

Knowledge is a sign of imamate 

The hadiths suggest various signs for Imams so that we can differentiate between the truly chosen Imams by Allah and impostors. One of the most significant signs is that he is the most knowledgeable person of his time. 

Prophet Muhammad (PBUH & HP) said:
Do not try to teach something to Ahlul Bayt because they are far more knowledgeable than you. (4)
Regarding this, Imam Sadiq (AS) acknowledged:
Indeed Ali (AS) was a knowledgeable person whose knowledge will be passed to his successors and no knowledgeable person (an Imam) dies except to leave their knowledge to someone else. (5)
He also said:
The successor of an Imam attains the knowledge of the previous Imam in the last moment of his life. (6)

The debates of Imam Javad (AS) with religious scholars

Ma’mun was one of the Abbasid Caliphs who lived during the same period as Imam Reza (AS) and Imam Jawad (AS). During his caliphate, the Shia population increased dramatically which intimidated him. Due to this fact, he lied that Imam Reza (AS) was his successor and led people to believe that he was not an enemy of Shiite Imams. But at last, he killed Imam Reza (AS). After Imam Reza (AS), Imam Jawad (AS) was his most important enemy. He made Imam Jawad (AS) marry his daughter so that he could deceive people longer. 

Many of the Abbasid royalties were against Ma’mun’s decision, as they believed that the boy was too young and he wasn’t a knowledgeable person. Ma’mun proposed that they should test the knowledge of Imam Javad (AS), in order to show everyone how extraordinary he is. Imam Javad (AS) was only nine years old at that time. 

One of the most knowledgeable religious scholars in those times, Yahya ibn Aktham, volunteered to have a discussion and debate with Imam Javad (AS). 
During the discussion, Yahya ibn Aktham asked Imam Javad (AS) about a person who has killed an animal while making Hajj; what should he do? (During the Hajj ceremony, it is forbidden for the pilgrims to kill any creature).
Imam Jawad (AS) said that it depends: Did he kill it in Mecca or outside of it? Did he know about this law or not? Has he done it intentionally or unintentionally? Was he free or was he a slave? Was it his first time? Was it a bird or something else? Was it a small animal or a big one? Is he ashamed of what he did or not? Did he do it at night or during the day? Was it Umrah (a special type of Hajj) or regular Hajj? 
Yahya was so surprised that he couldn’t answer the twelve questions of Imam Jawad (AS), but instead, Imam Javad (AS) answered them one by one and explained the rules to everyone. 
Ma’mun told people that “Now do you see what I was telling you?” (7)
During another session, Yahya asked Imam Jawad (AS) about a hadith from the Prophet (PBUH & HP) that Sunni narrators had recorded. The hadith said “Once Gabriel came to the Prophet (PBUH & HP) and told him ‘O Muhammad! Allah told you to inform Abu-Bakr that I am satisfied with him. Is he satisfied as well?” Yahya questioned Imam Javad (AS) about the authenticity of this hadith.
Imam Jawad (AS) said, “I do not deny the privileges of Abu-Bakr … but this hadith is contrary to the verses of the Quran.” Imam Javad (AS) stated he wouldn’t deny the privileges of Abu-Bakr because he was surrounded by Sunnis and it was so dangerous for him to speak out against Abu-Bakr.
Then he said, “The holy Quran says 
‘Surely We have created man, and We know the promptings of his heart, and We are nearer to him than even his jugular vein.’ (50:16) 
Then why should Allah ask Abu-Bakr whether he is satisfied with him or not while Allah already knows it?”
Yahya referred to another hadith that claims Abu-Bakr and Umar on the earth are like Gabriel and Michael in the skies. 
Imam Javad (AS) said “This hadith cannot be accepted as well, because Gabriel and Michael never worshiped anyone except Allah, while Abu-Bakr and Umar spent most of their lives as polytheists and worshippers of idols.” 
Yahya added that Abu-Bakr and Umar are the lords of the elderly in Paradise.
Imam Javad (AS) stated that it is impossible as people in Paradise are all young not old. Umayyad dynasty made this fake hadith because they didn’t like the authentic one narrated by the Prophet (PBUH & HP) that reads, “Hassan (AS) and Hussain (AS) are the lords of young people in Paradise.” (8)
Yahya said it also has been narrated that Umar is the one who illuminates Paradise.
Imam Javad (AS) responded that it is also impossible. Do you think that Paradise is not illuminated by the Angles and Prophets like Adam (AS) and Muhammad (PBUH & HP) but rather by Umar?!
Yahya said it has been claimed that the angels talk with the tongue of Umar.
Imam Jawad (AS) said that he does not deny the privileges of Umar. However, Abu-Bakr was better than Umar as he said, “I have a Satan that sometimes tempts me, so if you see me deviating, stop me.” 
Yahya asked many other questions about Abu-Bakr and Umar, and Imam Javad (AS) answered them all. (9)   
Not only Imam Javad (AS) did not fail to answer the questions, but also, he posed more questions that even the most knowledgeable scholars felt incapable of disputing with Imam Javad (AS). These debates happened when Imam Javad (AS) was only 8 or 9 years old. 
As it might be apparent, Shiite Imams were extraordinarily knowledgeable, and their knowledge was given to them by God not by learning in classes and the like. They were the most knowledgeable individuals in their era regardless of their age.

Visiting the tomb of Imam Hussain (AS) has been popular among Shiites since the time of the Shia Imams who taught Shiites that this pilgrimage plays a significant role in a Shia’s life as quoted from regard Imam Sadiq (AS) in this regard:

Do not pull back from going to Karbala for visiting the shrine of Imam Hussain (AS) out of insecurity or fear because anyone who does, will regret it so much that he wished the grave of Imam Hussain (AS) was near to him. Don’t you like to be one of those for whom the Prophet (PBUH & HP) and Imam Ali (AS) and Lady Fatimah (AS) and the Imams pray? (1)

Having a significant impact on every aspect of our lives, the Shia Imams encouraged us to fulfill this pilgrimage. such a great event which has been discussed and studied through so many aspects for example its history, its political and social impacts and so forth; but seldom have its moral effects on our personality been examined. Arbaeen pilgrimage may change our individual and social life in so many ways from which we’re going to mention some in this text.

The Impact of Arbaeen 

To Purify our Souls 

To purify soul in Islamic culture means changing our personality in a way that we obtain so many virtues and redeem our souls from bad habits or sins. Experiencing a very spiritual and calm atmosphere during this journey, anyone can revolutionize their lives and repent from all of their sins. 
Imam Sadiq (AS) said:

Should anyone leave their house in order to visit the grave of Imam Hussain (AS) Allah blesses them with a reward for each step they take if they go on foot and forgives one of their sins. (2)

To Practice Patience and Endurance 

Imam Hussain (AS) himself is the emblem of patience and endurance as he sacrificed all he had for the sake of Allah even his own life but he didn’t surrender to the tyrant oppressors. He and Lady Zeinab (AS) showed us how much a human can be patient facing the intolerable hardship that happen in their life. Imam Hussain (AS) even chose his companions from the most tolerant ones so that they could accompany him on his journey. For that matter, once he said to his people:

Anyone who is able to resist the sharp edges of swords and the invective of tongues can come with us and anyone who doesn’t must leave us (3) 

Nowadays although Iraqi people have made it so much easier for the pilgrims, taking this trip to visit Imam Hussain’s holly shrine (AS) is still full of dangers and hardships . When the pilgrims undergo these difficulties and think about the patience that Imam Hussain (AS) and his companions had, they can practice how to be patient in their own life. 

Self-esteem

When a pilgrim puts their heart and soul into reach a certain destination which is the land of Karbala to pilgrimage Imam Hussain’’s shrine on their way they endure so many problems and difficulties, they understand what a human is verily capable of. They can find out that life isn’t just the material world that we see around us but humans  are able to see something more in this life and sacrifice all they have for it. It makes people value their souls, believe in themselves and raises their more self-esteem. 

The Impact of Arbaeen Pilgrimage on our Social Life

Infaq and Generosity  

In Islamic culture, “Infaq” means helping people by giving charity, spending your time for them or even teaching others for free and stuff like that . 

During Arbaeen rituals , money isn’t an important issue for the pilgrims as people’s needs are mostly provided by others in Iraq. Most of Iraqi people even save money for a year so that they can help the pilgrims during the Arbaeen rituals with food, medicine and so forth. 

This enthusiasm for Infaq roots in the Islamic teachings and the messages of the Quran where says:
The parable of those who spend their wealth in the way of Allah is that of a grain which grows seven ears, in every ear a hundred grains. Allah enhances severalfold whomever He wishes, and Allah is all-bounteous, all-knowing. (2:261)

Also about the importance of the Arbaeen walk Imam Sadiq (AS) says:

For each coin that they spend for the sake of Imam Hussain (AS) Allah will consider it ten thousand coins and rewards them as they have spent that much and Allah will be pleased with them and the Prophet (PBUH & HP) will pray for them and Imam Ali (AS) and the Imams will do so. (4)

Cooperation and Empathy

The holy Quran says:

Cooperate in piety and God-wariness, but do not cooperate in sin and aggression, and be wary of Allah. (5:2)

Arbaeen walk is a symbol for a society in which people with different ideas, nationalities, ethnicity colors, age groups, and religions work together to reach one common destination. The objective of all these people is the same and it’s making Allah pleased with themselves by commemorating the sacrifice of Imam Hussain (AS). People respect each other and help just for the sake of Allah.

Political Insights 

Pilgrims in this ceremony think more about the message of Imam Hussain (AS) which was justice and fighting against tyranny, violence, and doing sins. Imam Hussain (AS) himself says:
I didn’t start this movement so that I could achieve a status among people or to please my desires. I didn’t do it to create chaos or to oppress. I started this movement so that I could make the followers of my grandfather better people; I want to enjoin others to do good works and prevent them from doing sins and I do as my grandfather and my father did. (5)

This walk helps us change ourselves and the others and understand that sitting down and watching people being in pain and oppressed is not what Allah wants us to do. We all are responsible for the circumstances in our society.
