We are far ahead of the time when people lived in actual social networks. People living in a town or village were in a strong relationship with one another, and of course, it served them well.
But, maybe people were too closely related back then. And it had its downsides, too. “Give me a break, please, I need some privacy!” That’s what we said to the social life of the past times. The modern way of life ascribed so much importance to our privacy. This, too, had its downsides and sometimes made us feel so lonely. It didn’t quench our need to see and be seen. We needed to share more.

An Exciting Invention… 

But, modern life and technology also had the answer to that. They provided an unaccountably cheap and easy way of making relationships, without the need for getting quite out of our private zone; virtual Social Networks!

Well, that’s great! We can get to know about our family and friends without spending much time or money. We can easily make thousands of friends from around the world. We can share our ideas and lifestyle with them and get to know about theirs. Like all other inventions, there are many good ways to benefit from social networks. And there being many good ways to benefit from something, is somehow equal to its lawfulness in Islam. 

“… who bids them to do what is right and forbids them from what is wrong, makes lawful to them all the good things and forbids them from all vicious things…” (7:157).

Social Networks in Islam: Rules Apply!

But is using social networks in Islam forbidden? Does Islam have any special resistance to these networks? Well, not really. And the rules on what we should do and what we should try to avoid are pretty much the same as the ones we need to observe in actual communications.

Therefore, as we are always careful to avoid any harm in our actual relationships [1], we should also do the same in these virtual sites of getting together, and try not to go for the bad things that might be found in there, nor spread things that might do more harm than good to others or to the society. 

That means even if it is a boy-girl or man-woman relationship, there is nothing wrong with it as long as it is an upright, righteous, and honest one, and as long as you observe modesty and the rules of covering, the same way as a relationship between men and women in the outer world.

Also, Islam very much calls us up to mind the circles we move in [2], which are, more or less, a representation of our character and inclinations! Do our friends and groups in social networks –as well as in the real world– help us and change us for better? Or that they are just fun for a short time and may bring us lasting sorrows and regrets? [3]

Slippery Road… Watch Your Steps!

You might have noticed that conventional social networks, being inherently so cheap and easy, tend to make everything cheap and easy in all respects… and maybe too much so sometimes!
Suppose you share a highly valuable and precious post on Facebook –which is the easiest way to share it, of course– and your friends would barely spend five seconds to look at it! 

We are in the habit of taking everything easy in these virtual places; even our relationships. We don’t care that much about what we see or share, and sometimes about the kind of relationships we are making, while, to the contrary, a Muslim is always required to be watchful of his or her doings! [4]

So, apart from the benefits of being cheap and easy for use, they also make it easier to lie, to pretend, or to do any wrong. We may not be quite conscious that some of our relationships in the social networks could be, more or less, a kind of betrayal of our wedlock! Or a little too open to be modest and righteous! For, according to Islam, a husband’s level of modesty affects that of his wife and vice versa. [5] That means, the more righteous a spouse, the more so will be the other! That’s why it is even more important here never to forget that, little as it may be, a wrongdoing is always wrong, whether in a virtual social network or out there in the real world. 

“So whoever does an atom’s weight of good will see it, and whoever does an atom’s weight of evil will see it.” (99:7,8)

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.
