Ramadan is the 9th month of the Islamic calendar. The root of the word in most of the dictionaries refers to strong heat or burnt earth. Some commentators use this meaning to refer to the heat and hardship that people endure during Ramadan fasting. However, there is another meaning for the root of the Arabic word “Ramadan” which refers to the clouds and the rain at the end of summer and beginning of fall. [1] Prophet Muhammad (PBUH&HP) says: “Indeed, it is called Ramadan because it burns the sins”. [2] In this narration both meanings can be adopted, since based on the first meaning it burns the sins, and based on the second meaning, it quenches the fire that is the consequence of sins.

 Contemplating on the verse of the Quran “The month of Ramadhan is one in which the Quran was sent down as guidance to mankind, with manifest proofs of guidance and the Criterion…” (2:185), one can conclude that the second meaning that was mentioned for the word “Ramadan” is more suitable to describe this month; a month in which blessings and bounties of Allah (SWT) shower on His servants. One of those blessings as mentioned in the above verse is the Holy Quran which was revealed in Ramadan on the greatest night of the year: “Indeed We sent it down on the Night of Ordainment” (97: 1). In another verse, Allah (SWT) mentions, “We sent it down on a blessed night.” (44:3)

The three mentioned verses have some points that can help us think and discover if the month of Ramadan became a holy month after Prophet Muhammad (PBUH&HP) brought Islam, or was it always a holy month throughout history? 

What does the Quran tell us about the history of Ramadan?

As mentioned in the above verses and other verses of the Quran, Allah (SWT) tells us that:
1-    The Quran was revealed in the Holy month of Ramadan. (2:185)
2-    The Quran was revealed on the night of decree. (97: 1)
3-    The night of decree is so high in a position that no normal human being can understand its status and value: “And what can make you know what is the Night of Decree? The Night of Decree is better than a thousand months.” (97:2-3) 
4-    According to verse 44: 4, every firm ruling is dispatched on that night. These rulings are the decrees concerning the way the affairs of the world should run until the same time next year. Such a concept which is related to the creation should have been an eternal matter and could not have come about just by the advent of Islam. 

By doing simple math on the above verses, we can conclude that before the Quran was revealed, the night of decree existed as a blessed night, and by Allah’s will the Quran was revealed in this blessed night. Therefore, Ramadan always existed as a blessed month in which the night of decree has always been a prominent night. 

History of fasting 

The word fasting is mentioned a few times in the Quran when Allah orders Prophet Zachariah (PBUH) and Saint Mary to avoid talking to people: “Then if you see any human, say, ‘‘Indeed I have vowed a fast to the All-beneficent, so I will not speak to any human today.’’ (19:26) 

The above verse shows that there have been different traditions of avoiding specific things, which has been called fasting. However, the verse of the Quran that makes fasting an obligation on Muslims says: “O you who have faith! Prescribed for you is fasting as it was prescribed for those who were before you, so that you may be Godwary.” (2:183)

The commentators of the Quran have disagreed about the purport of this verse. Some argue that the phrase as it was prescribed for those who were before you is referring to the concept of fasting only. It means that the previous nations were told to fast like you are told, however, the verse is silent about the time or the way of their fasting. Others, say that as it was prescribed for those who were before you means that the fast of Ramadan was prescribed for them exactly in the same way that it is prescribed for you. 

Looking into the rules and descriptions of fasting in Christian and Jewish traditions would certainly support the first view since neither of these religions have fasting in Ramadan as part of their traditions. However, some commentators, quoting Hasan al-Basri have argued that the verse refers to Christian fasting which was originally ordained to be in Ramadan but they changed it over time. They say that fasting during the Lent season which in Christian tradition is related to the testing of Jesus in the wilderness is not the original concept of fast in Christianity. Rather, what was originally prescribed for them was the fast of Ramadan, but since as a lunar month it circulated over different seasons, the leaders of the church decided to fix it in the spring and add ten days to it as an atonement for such a change. It was then called Lent and related to the 40 days of Jesus’s tests in the wilderness.

However, we have to regard this as an odd view, since nothing in history can support such a development. Thus, as most of the commentators say, as it was prescribed for those who were before you, means that people of previous Scriptures were also told to fast, although not exactly in the month of Ramadan. 

However, there is a third view here which can be regarded as a combination of the above two views, and as a view that makes the sanctity of Ramadan of a primordial nature. It is narrated from Imam Sadiq (AS) that “Allah (SWT) has not made fasting of Ramadan compulsory on any nation before Muslims.” He was asked about the interpretation of the verse “as it was prescribed for those who were before you”, where he replied: “Allah had made fasting of Ramadhan compulsory on the Prophets before you, but He prioritized this nation by it and made fasting an obligation on the Prophet and his followers.” [4] This means although fasting of Ramadan was not prescribed for previous nations, the past prophets used to honor Ramadan by fasting during the month. Something similar to this is reported about Hajj too. It is narrated that although Hajj is an exclusive obligation of the nation of Islam, however, prophets of the past nations including Moses and Jesus performed Hajj.  

It is also narrated that the first Prophet who fasted was Prophet Adam: “when Adam ate the fruit of the forbidden tree, that fruit remained in his stomach for thirty days, and it was then that Allah made the thirty days of fasting obligatory on Adam and his generation.” [5] 

In conclusion, what could be firmly said, is that fasting is not an obligation specific to Muslims only. All nations who received Scriptures were also told to fast like Muslims are told to fast, although the details about how and when they must fast may have been different.

At the beginning of Islam, the number of literates in the whole Mecca was about 17 people (1). In those times, it was even considered as a shame to be able to read or write (2). In the ancient times, people mostly weren’t able to read and literacy was the exclusive privilege of the royal families or rich people. However, in the Arabia, even the royal families couldn’t read or write. Once, Prophet Muhammad (PBUH & HP) wrote a letter to “Bakr ibn Va’il”, a large Arab tribe, and enjoined them to believe in Islam; but when they received the letter, they weren’t even able to read it (3).
In spite of these shameful circumstances, Allah al-mighty sent His most important apostle to the people with only a book as his miracle. The first verses of the Quran, revealed to the Prophet (PUBH & HP), are about reading:
Read in the Name of your Lord who created; (1) created man from a clinging mass. (2) Read, and your Lord is the most generous, (3) who taught by the pen, (4) taught man what he did not know. (5) [96:1-5]

Knowledge and Literacy in Islam

Muslims differentiate between the era before the Messenger (PBUH & HP) and the era after him based on peoples’ knowledge. We call the time before the rise of Islam “The Ignorance era”. 
The holy Prophet (PBUH & HP) taught people that knowledge is the criterion that sets them apart   . The Holy Quran says:
Say, ‘Are those who know equal to those who do not know?’ Only those who possess intellect take admonition (39:9)
About learning, the Holy Messenger (PBUH) says:
 Seek knowledge even if you have to go to China to find it. (4)
Imam Ali (AS) also highlights the Importance of knowledge in his speech with one of his companions:
O Komeil! Knowledge is better than wealth, because knowledge protects you. But for wealth, you have to protect it. Wealth and money get less when you spend them, but by using your knowledge or by teaching it to others you even get more knowledgeable … O Komeil! The ones who love wealth excessively, are like dead people (spiritually) even if they are alive (Physically). However, the spirit of knowledgeable ones will always be alive in the hearts of people even if their bodies are dead. (5)
The Holy Messenger (PBUH & HP) even considered learning as “Vajib” which means that learning is an obligation for every Muslim:
Seeking knowledge is an obligation for every Muslim, men and women (6)
One of the clearest signs that shows the Prophet (PBUH & HP) wanted everybody to be literate and knowledgeable is that he ordered the slaves after the Badr war to teach the children of Medina to read and write and in return, the slaves would be free. (7)

Keeping the Knowledge Safe

The Holy Quran says:
By the pen and what they write (68:1)
We all know that without writing, we weren’t able to communicate our thoughts and ideas with each other and we couldn’t keep them for future generations. In this regard, the Holy Prophet (PBUH & HP) says:
Keep your knowledge safe.
Some people asked:
How can we do that?
The Prophet (PBUH & HP) replied:
By writing it! (8)
Moreover, Imam Sadiq (AS) said to one of his pupils, Mufazzal ibn Umar:
Write and spread your knowledge among the people and if you were going to die, leave your writings for your children because there will be a chaos in the future and in those times, people will not find any peace except in their books (9)
He also said:
Keep your writings because you will need them in the future (10)
Imam Hassan (AS) would gather his children,his niece and nephews and tell them:
You may be considered as kids now, but it is so likely that you will be the elders of many groups and families in the future. Therefore, it is your duty to seek for knowledge. And if there are some people among you who cannot memorize their knowledge, they must write and put their writings in their houses and keep them safe. (11)

Carriers of Books

Action and knowledge are inseparable in the Islamic view. If you act without having enough knowledge and data about the work you’re going to do, you will spoil it and your efforts will be in vain. Imam Sadiq (AS) says:
The one who acts without having enough knowledge is like a passenger who goes on the wrong road. So they get farther and farther from their destination as they go faster and faster. (12)
On the other hand, knowledge without acting is also useless. Imam Ali (AS) says:
Knowledge without action is like a tree without fruit or like a bow without its string (13).
The Holy Quran also says:
The example of those who were charged with the Torah (Old Testament), then failed to carry it, is that of a donkey carrying books. Evil is the example of the people who deny Allah’s signs, and Allah does not guide the wrongdoing lot. (62:5)
