The concept of the last savior and his advent exist in many religions, although with some fundamental differences. Here we review what expecting the last savior in Islam means, what are its requirements and how it improves the quality of one’s life. 

1. Hoping for a Widespread Evolvement through the Last Savior in Islam

Awaiting, in general, represents a situation where someone is hoping or watching for something to happen, especially for a long time. Awaiting the last savior means hoping for the last divine messenger who will reveal the truth and spread justice and peace in the whole universe. In Surah Qasas, it is stated that: “We wanted to confer a favor upon those who were oppressed in the land and make them leaders and make them inheritors” (28:5). This is a promising divine concept which enlightens the hearts, prepares human beings for receiving who they are waiting for, and brings hope to them [1]. 

2. Not Standing the Current Circumstances

We are surely living in an era that is filled with injustice; some people are at war, and many of them face discrimination and hypocrisy. From an Islamic point of view, even the physical presence of the last savior brings mercy over human beings, and all these shortcomings are due to his absence. Hence, a conscious human being, a creature that is a perfectionist in nature, does not tolerate these shortcomings and defects and tries to remove the barriers against the presence of the last savior. 

3. Hoping for a Better World 

Being a perfectionist and trying to achieve a better condition is an inherent quality of the human beings that regulates almost all activities of every human being towards perfection. Hence, a conscious human being is naturally inclined toward accelerating the coming of the last savior.

4. Making Efforts to Pass the Current Unfavorable Condition and to Reach a Desirable Situation 

Hoping for a better future that the presence of the last savior will bring about is not sufficient. One should also make efforts and participate in the process of preparing the requirements of the advent of the savior.

5. Being Aware of the Absence of the Last Savior

Sometimes something is missed in our life, but we are not even aware of that. The very first step in the process of awaiting the last savior is to know that there is divine mercy that is absent.

6. Feeling the Need for the Advent of the Last Savior

One might be aware of the absence of the last savior but does not believe that human beings require his presence and guidance. Hence, waiting for the last savior requires one to contemplate and know what his presence will bring about for human society. In fact, this situation is like a divine test to see whether one will rely on his\her abilities and will to improve the current condition.

7. Believing in and Wishing for the Future Coming of the Last Savior

Those who do not believe in the advent of the last savior will undoubtedly not await for him. Prophet Muhammad (PBUH&HP) and Imams (AS) have always tried to reinforce the belief in the advent of the last savior and to prevent any despair among human beings. In this regard is a narration (hadith) from Prophet Muhammad (PBUH&HP), which describes that The Judgment Day will not arrive until one of his descendants rises with the truth and makes his advent whenever Allah permits [2]. One who believes in the advent of the savior in Islam should also wish that it happens, otherwise, he\she is not really awaiting his advent. This requires having a clear vision of the things that will happen if the last savior emerges. If one is afraid of that time, he\she will surely not await for him to come.

8. Believing that the Advent of the Savior Is Close

Although the items above make one await for the savior, believing that this might happen very soon will cause one to get ready to help the last savior in Islam in his peace plan.

Human beings are created to be free and choose what to do with their own lives. However, sometimes the path toward growth is not through being free to have whatever we desire but to abstain from what we really wish while it is deviating or is a barrier against reaching the perfect version of ourselves. Here, the history of fasting finds its meaning. This is a ritual in which one, by his/her own free will, chooses to abstain from certain activities; this could range from not eating or drinking for a specific time, etc. Many faiths and religions, throughout history, encouraged their followers to fast in a certain way, each aiming at the spiritual elevation of their adherents. Islam is also among those religions which have made fasting an obligation upon its followers under certain circumstances, accepting the fact that this was not a tradition unique to Islam: 

"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." Quran (2:183)

In what follows, we will have a look at the practice and history of fasting in the five most prominent non-Abrahamic faiths. 

1. The History of Fasting in Primitive Religions

Looking at the history of fasting in primitive tribes and cults, we find some evidence regarding their belief in the spiritual impact of fasting and "was a practice to prepare persons, especially priests and priestesses, to approach the deities." Some Hellenistic cults believed fasting to be the prerequisite for reaching divine revelation for their priests. Some others thought that fasting "was one of the requirements for penance after an individual had confessed sins before a priest." [1]
Fasting was also common among Native Americans, practiced in private, or as a part of public ceremonies. The individual fasting often included the ones who had recently entered puberty, and they had to spend some time alone, from one to four days. During this time, they had to reach a particular spiritual maturity by observing certain rituals. Also, "It was not uncommon for an adult to fast, as a prayer for success when about to enter upon an important enterprise, as war or hunting" [2]. Moreover, fasting was considered a requirement for religious heads to be able to fulfill their duties. The public fasting happened as a part of the initiation into religious societies, the length of which "ranged from midnight to sunset, or continued for four days and nights." The fast of these ancient tribes often included abstinence from food and water. The Native Americans saw fasting as "a means to spiritualize human nature and quicken the spiritual vision by abstinence from earthly food… as a method by which to remove "the smell" of the common world." [2]

Ancient Egyptians and Babylonians also practiced abstinence from food and drink as "a form of penance that accompanied other expressions of sorrow for wrongdoing. Like people of later times, these nations viewed fasting as meritorious in atoning for faults and sins and thus turning away the wrath of the gods." [3]

2. Fasting in Hinduism 

The Hindu faith also includes some form of fasting, which is ultimately aimed at spiritual awareness and growth by forming a balanced relationship between the body and the soul. Hindus believe that fasting can be a means of concentration on spiritual attainment through abstaining from worldly indulgences and distractions. Another purpose of fasting in Hinduism is self-discipline, which is made possible through "training of the mind and the body to endure and harden up against all hardships, to persevere under difficulties and not give up. According to Hindu philosophy, food means gratification of the senses, and to starve the senses is to elevate them to contemplation." [4] 

Hindus have specified certain days for fastings, such as Purnima (full moon) and Ekadasi (the 11th day of the fortnight). Moreover, depending on the god or goddess each individual worships, certain days of the week are dedicated to fasting. They also fast on special feasts and festivals, including "Durga Puja," "Navaratri, Shivratri, and Karwa Chauth. Navaratri is a festival when people fast for nine days." [4] It is noteworthy that some kinds of fasting in Hinduism are only obligatory for women.  

3. Fasting in Buddhism

The practice of fasting in Buddhism is seemingly limited to monks and religious leaders. It is said that the Buddha had undergone long periods of fasting during the time he was learning from other teachers as a kind of self-mortification. While there is no record for Buddha's fasting after this time or his recommendation for fasting to his followers, many Buddhist monks tend to fast on certain occasions as a way of self-purification and spiritual elevation. They would eat only one meal a day and would fast on the days of the new and full moon. 

As a part of Buddha's concept of moderation and avoiding excessive manners, intermittent or prolonged fastings are not encouraged in this faith. However, fasting for a reasonable amount of time and refraining from excessive eating is considered a useful way of preserving health in Buddhism. [5] In general, fasting in Buddhism is limited to refraining from eating solid food, such as meat.  

4. Fasting in Daoism

Daoist's concept of fasting is more about mind rather than the body. Therefore, they encourage a form of "fasting of the heart" (xinzhai), which will result in a more pious life [3]. However, they also believe that the fasting of the body will ultimately result in a clean body and a pure soul. In the book of Mencius, one of the famous Chinese scriptures, fasting is considered as a means of self-purification even for the one who has darkened his/her soul by vices:
"But although a person is ugly, it is possible, through fasting and purification, to become fit to perform sacrifices to the Lord-on-High" [6] 

In this tradition, one must avoid doing any evil deed and keep away from harmful hobbies and desires. The followers of this tradition try to read more of their religious scriptures as they fast to connect more to that Higher being and find peace [7]. 

Zhang Yuchu wrote in the Ten Daoist Commandments: "Anyone cultivating Dao must fast for a clean body as well as a pure heart, and he must visualize the spirits and read Daoist scriptures silently in his mind. It is as if facing the Higher Emperor, communicating with him with the heart." [7]

5. Fasting in Zoroastrianism

It seems that most Zoroastrians implicitly reject the practice of bodily fasting, which in their view would weaken the body and prevents one from appropriately attending his/her spiritual duties and satisfying physical needs [8]. The only form of fasting which they find permissible "is that of abstaining from sin" [9]. There is also a reference to this prohibition in Avesta, the religious Zoroastrian text:

"It is requisite to abstain from the keeping of fasts. 2. For, in our religion, it is not proper that they should not eat every day or anything, because it would be a sin not to do so. 3. With us, the keeping of fast is this, that we keep fast from committing sin with our eyes and tongue and ears and hands and feet. 4. Some people are striving about it, so that they may not eat anything all day, and they practice abstinence from eating anything. 5. For us it is also necessary to make an effort, so that we may not think, or speak, or commit any sin; and it is necessary that no bad action should proceed from our hands, or tongue, or ears, or feet, which would be a sin owing to them. 6. Since I have spoken in this manner, and have brought forward the fasting of the seven members of the body, that which, in other religions, is fasting owing to not eating is, in our religion, fasting owing to not committing sin." [10]

However, there is a tradition of fasting in this religion at the time of mourning for a departed soul, which is only limited to not eating meat. As the Avesta suggest:

"In every habitation where anyone departs, passing away from the world, it is necessary to endeavor that they may not eat and not consecrate fresh meat for three days therein. 2. Because the danger is that someone else may depart, passing away; so the relations of that former person should not eat meat for three days." [10]

So far, we have reviewed the history of fasting in five well-known non-Abrahamic faiths, which reveals the spiritual roots of this practice from the beginning of the time. In the next article, we will study the ritual and history of fasting in three Abrahamic religions; that is Judaism, Christianity, and Islam.
