The Holy Quran is said to be "the highest miracle of Islam". But why would a book turn out to be the proof of Prophet Muhammad’s (PBUH) prophethood? What does it reveal about Islam's attitude toward the issue of learning or seeking knowledge?  How does a true Muslim seek knowledge?

There are many verses in the Quran about acquiring knowledge. The very first verse of the Quran that was sent to our Prophet starts with an imperative form of the verb "read" (Ighra) [1]. Literacy and having knowledge is so important in Islam that Quran equals illiteracy to being in darkness [i]. Accordingly, it is the duty of any Muslim to try to learn. Besides, many Islamic scholars advise Muslims to strive for achieving knowledge. One of them is a quotation (hadith) from Prophet Muhammad (PBUH&HP): “Seek knowledge, even if it is in China”. Considering the distance between the Arabian Peninsula (where the Prophet lived) and China as well as the lack of transportation 14 centuries ago, one can imagine how arduous it was to travel there. In addition to many life-threatening dangers, it is no exaggeration to say that it took several months to arrive there. This shows the emphasis on the importance of learning.

When the prophetic mission of Prophet Muhammad (PBUH&HP) started, most people in his land were illiterate, so, he asked the literate ones to teach Muslims; even prisoners of war were granted freedom provided that they taught literacy to at least ten Muslims. It has been said that once, the Prophet (PBUH&HP) entered a mosque and saw two groups of people; one group was praying and the other was sharing knowledge. He stated that both of them were doing a good job, and then continued his speech by saying that he was sent to people by God “to teach” them. So he went and sat in the second group [2]. When Prophet Muhammad (PBUH&HP) was alive, there were places like schools where both women and men had the freedom to take part in classes. And, different fields of knowledge were learned including religion, literature, poetry, rhetoric, medicine, astronomy, etc [3].

A human being is curious by nature. We have been created with an inquiring mind. It has been said that all human beings are bestowed a gift, that is the brain as well as the desire for learning. The desire to learn is in our nature [4]. In Islamic instructions, there is a huge emphasis on the value of seeking knowledge. It has been quoted from Prophet Muhammad (PBUH&HP): “Seek knowledge from the cradle to the grave”. It is a must for every Muslim regardless of their age, race, or gender [5]. All people must have the ability and liberty to learn, teach, exchange, and share information. It does not matter from whom you are learning. As long as they have the knowledge, it would be perfect. There is an Islamic hadith from the fifth Imam of Muslims, Imam Muhammed Al-Bagher (AS), quoted from Jesus Christ (AS) saying that: “Learn knowledge from someone who has it and does not look at their deeds.” There is no kind of prejudice whatsoever in choosing the teacher. The only important thing is the learning itself. Besides, ignorance has been known as the root of many miseries; and knowledge is like a vast amount of treasure that never runs out.

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.
