Ramadan is the ninth month of the Islamic calendar, observed by Muslims worldwide as a month of fasting, prayer, reflection and community. In this holy month Muslims fast from the food, drink, smoking, and sexual activity, and other specific activities drawn by Islam between dawn to nightfall until when the evening adhan is sounded in order to practice abstaining. There is definitely a higher purpose beyond not eating or drinking behind fasting. Fasting is one of the Principles of Islam, a religious duty commanded by Allah. Muslims who obey such commands or duties are said to receive thawab* each time for each good deed and receive redemption in the afterlife. Today we are going to discuss the real philosophy behind this Principles but at first, let us see some of the Quran verses pointing to fasting and its place in Islam. 

Almighty Allah says: 

O you who have believed, decreed upon you is fasting as it was decreed upon those before you that you may become righteous – 
(The Holy Quran 2:183) 

Also:

The month of Ramadhan [is that] in which was revealed the Qur'an, a guidance for the people and clear proofs of guidance and criterion
(The Holy Quran 2:185)

The high purpose of Fasting

This principle is often emphasized in the principles of Islamic jurisprudence “The basis for the formation of all religious and divine rules is the interests and corruptions that philosophy is its cause”. 

The second surah of The Quran (Al-Baqarah) clearly telling us the purpose of the act of fasting, talks about Divine bowing (verse 185), thanksgiving (verse 185), Benefiting from divine help (verses 45 and 153), benefiting from Allah (verse 184), attaining piety (Verse 183) and victory and success in deeds (verses 45 and 153) are among the wisdom and goals of fasting. We will discuss them deeply now:

1. The test of sincerity

Fasting has other benefits and effects, the most important one is identifying the sincere; Because fasting means abstaining from drinking and eating and sexual pleasures as well as other prohibitions, it is very difficult for many people who cannot wash their hearts of material pleasures and are only humble and submissive who give up by divine command. Therefore, it can be said that fasting is one of the most important divine tests through which sincerity can be recognized. Imam Ali (AS) says about this function of fasting: Allah made fasting obligatory in order to test the sincerity of the people. (1) Also, Lady Fatemeh (AS) says about the role of fasting insincerity: Allah has made fasting obligatory in order to establish sincerity. (2)

2. Fasting and empathy with others

Other functions of fasting include the element of empathy; Because the fasting person understands the difficult conditions of others by fasting, and because of the suffering he suffers during the fast, he feels the suffering of the poor deeply now. Creating similar conditions and assimilating the living space with the lives of the poor, in the most important dimension, namely the lack of food and drink and other pleasures, causes a feeling of sympathy and provides the ground for financial benevolence and charity. Some rich people, for various reasons, including illness or intentionally not fasting, have to pay atonement, so one of the purposes of fasting is to reach a part of the wealth and property of the rich to the poor so that at least the life of the poor is provided and the level of class distance becomes slightly lower.

we can also refer to this wisdom that Imam Sadigh (AS) has stated about the obligation of fasting: Allah has made fasting obligatory so that the rich and the poor become equal (3) Imam Reza (AS) also says about this matter: People are commanded to fast in order to understand the pain of hunger and thirst, and through it to find the poverty and misery of the Hereafter. (4)

3. Fasting, the Zakat (charity) of body

Another wisdom mentioned in the narrations for fasting is zakat of the body. In the sense that zakat is for everything; That is, just as it is zakat for property, which by paying for it provides the ground for proper growth and development of the body. Prophet Mohammad (PBUH&HP) said: Zakat is for everything and zakat on the bodies is fasting. (5) Also, our dear Prophet (PBUH&HP) said: Fast to stay healthy (6)

Medical research has proven today that fasting has a very effective role in eliminating diseases, especially cancer; this is because the lack of nutrients in the body has the first effect on cancer cells and dries out their roots. Therefore, in order to have a healthy body and all the organs of the body to work properly, we must accept fasting as a treatment and use it for the proper development of our body.

4. Fasting is a kind of Jihad

In the teachings of Islam, Jihad, especially its military one, has been set as a standard for other tasks due to its difficulty to achieve. Therefore, matters such as gaining halal, marrying well, and the like are considered and measured as jihad. Fasting is a difficult and arduous task because it is even permissible to step on carnal pleasures. Fighting against carnal desires and confronting erotic issues is one of the most important jihads known as the Great Jihad; and it is more difficult to fast in the heat of summer and under the sun and with work and labor. Such a fast is one of the best examples of deeds from the ideals of Prophet (PBUH&HP) that he said: Fasting in the heat is jihad. (7)

Imam Sadegh (AS) also says about fasting in extreme heat: Whoever fasts for Allah on a very hot day and becomes thirsty, Allah will appoint a thousand angels to touch his face and give him the good news until he breaks his fast. (8)

The best fast

Achieving true fasting means that not just a person's body and tongue fasting, but also his heart and mind are fasting. Imam Ali (AS) says in expressing the best types of fasts: The fast of the heart is better than the fast of the tongue, and the fast of the tongue is better than the fast of the belly (9). So, in the real fast, all the organs of a person must be fasting from sin and mistakes. It is also narrated from Lady Fatima (PBUH) that: What is the use of fasting for a fasting person who has not preserved his tongue, ears, eyes, and joints? ** (10) 

Conclusion

There is no point in Islam that hasn’t been checked by wisdom higher than human ones. If there are acts in Islam that are hard or pointless in our sight, that means we can’t see their higher purpose. Islam is always fresh and never gets old like other religions and it seeks human redemption so follow its orders to find yourself in the righteous path

Does the Quran have any direct verses about books? Can the Quran guide us on what kinds of books to read? How can a book that was revealed about 1400 years ago tell us about which book genres are useful and which are not? 
In this text, we will study the status of reading books in the Quran and in Islamic teachings.
The first thing about books is the fact that the Quran, the miracle of Prophet Muhammad (PBUH&HP) is a book. Therefore, there is no doubt that there are no problems with reading books in Islam. But, the question that if there is any limitations in reading different types of books is considerable. 

Pointing out about books in the Quran

The word book has been used a lot in the Quran and has been used for three different meanings. Yet, all of them are used for a thing that records concepts and meanings and transfers them to the audience. In all different meanings of the book, it has been mentioned as a medium. The three different types of books mentioned in the Quran are as follows: 

1-    The books that contain religious rules and laws. [1]
2-    The books that record the deeds and actions of people. [2]
3-    The book in which all the events and details of this universe have been written and is kept by Allah. [3]

Writing books

Writing books is also an important point in the eyes of the Quran, as books are crucial means of conveying messages and transferring history to the next generations. They are also great means of spreading knowledge, wisdom, science, etc. the status of books and writing are so high in the eyes of Allah (SWT) that there is a chapter in the Quran called “Pen” (Qalam) in which Allah (SWT) swears by pens and what is written by it. [4] 
However, it is also very important that the written content should be useful, based on truth, and produced for the growth and improvement of human beings: 
“So woe to them who write the Book with their hands and then say, ‘This is from Allah,’ that they may sell it for a paltry gain. So woe to them for what their hands have written, and woe to them for what they earn!” (2: 79)

This can be a very important lesson and point to all of those who use their writing talent and produce written material for their audience. The above verse shows how enormous the effect of written products are on the readers.  

What does the Quran say about reading books?

Reading is also a very important point that is mentioned in the Quran. The most unique verse of the Quran that shows the importance of reading is, according to some Islamic scholars, the first verse of the Quran that was revealed to Prophet Muhammad (PBUH&HP): 
“Read in the Name of your Lord who created; Created man from a clinging mass. Read, and your Lord is the most generous, who taught by the pen, taught man what he did not know.” (96: 1-5)

The above few verses show how learning knowledge and wisdom is connected to writing and reading. It is by writing that human beings transfer their thoughts and learnings to others, and it is by reading those writings that people learn from others. It is by reading that people think, contemplate, and come up with new ideas which lead to more learning, wisdom, discovery and inventions. Therefore, Allah compares those who seek knowledge and those who do not and asks us: 
“… Say, ‘Are those who know equal to those who do not know?’ Only those who possess intellect take admonition.” (39:9) 

Which books to read?

Despite the importance of gaining knowledge through reading in Islam [i], still we might ask if all the books available in the market are useful, worth reading and lawful (Halal) to read in Islam. 

The point is that the Quran does not mention all different book genres and does not discuss each genre in detail. But, it provides specific frameworks that work as a type of criterion. Knowing the criterion helps us to distinguish which books are useful for us and which ones can harm our soul and spirituality. 
For example, the Quran is not against stories or novels since the Quran itself is full of amazing stories, some of which are examples or stories [5]. Allah (SWT) claims that He is the best storyteller when He says: 

“We will recount to you the best of narratives in what We have revealed to you of this Quran, and indeed prior to it you were among those who are unaware [of it].” (12: 3)

Reading such books will result in many positive effects on our mind and soul. As Imam Ali (AS) says, “The greatest peace is obtained by reading books”[6]. Also, at the times of difficulties and hardships, sometimes one finds no remedy other than taking refuge in books, perhaps to find a way out; As Imam Sadiq (AS) puts, “There will be chaotic days when people would not find peace unless within their books” [7]. 

However, this does not mean that reading all types of storybooks, novels or myths are useful. Allah mentions in the Quran that real believers are those who “avoid vain talk” (23: 3). Therefore, books in which we can find parts that would waste our time or those that contain stories, chapters, or lines that may harm human soul and spirituality are not recommended to read. Apart from the books that may harm our soul, reading and learning can be considered as a sign of a Muslim.
