Faith in the religion of Islam is based on rational thinking. Quranic teachings always encourage people to achieve faith through reasoning and do not consider mere devotional cognition as adequate. Hence one should accept the Islamic axioms (Monotheism (Tawhid), Prophethood (Nubuwwah), and Afterlife (Ma’ad)) logically.

The above-mentioned Islamic axioms are constant, immutable, and limited, whereas new events and issues of each time are changeable and infinite. Consequently, there needs to be some Islamic scholars or experts who know the Islamic teachings in general and are aware of the contingent issues of the time and their solutions in particular, which makes them responsible for inference of new laws from basic principles of Islam (Ijtihad) in accordance with the needs of changing times and the requirements of new phenomena of human civilization [1].

On the other hand, the Integration of different people to Islam with their particular way of thinking, living with leaders of various religions, the religious discussions between them and the Muslims, and the appearance of Islamic philosophy would always arise doubts and uncertainties. So it necessitated research on the principles of Islam and justifying them especially after the time of the last Prophet (PBUH) and the Imams.

Muslim scholars have always proved that the Islamic teachings are dynamic, compatible with the passage of time, and capable of fulfilling the requirements of each age, generation, and civilization; this would, in consequence, develop the Islamic society and lead it through the path of evolution and perfection in many parts of the world, especially in the first centuries.

Ijtihad

The literal meaning of Ijtihad is to do one's utmost while striving and making effort to reach a goal which in this case is to endeavor to deduce the divine laws of Islam from the reliable sources and proofs, i.e. the Holy Quran, the historical tradition (Sunnah) [i], consensus (Ijma`) [ii], and reason (`Aql).

The term Mujtahid (the religious expert), derived from Ijtihad, refers to a person who endeavors in the way of Allah to derive laws and decrees regarding the religious fundamentals through all kinds of hardships and difficulties.

Ijtihad, which is of great importance in the religion of Islam, guarantees its persistence. Muslims have always been urged to study Islamic science and everything else which is necessary for the development and well-being of their society.

However, it is not compulsory (Wajib) for every single Muslim to become a religious expert (Mujtahid) due to its difficulty and some people’s inability to comprehend and derive Islamic laws all by themselves. It means that the obligation is on the community as a whole and so when a group of people devote themselves to the science of religion to guide the Muslims, then the obligation is lifted from the rest of the society [2].

Quran says: “why should not there go forth a group from each of their sections to become learned in religion, and to warn their people when they return to them, so that they may beware?” (9:122)

It is noteworthy that even though it is a sufficiency duty, every single person in the Islamic community can learn the science of religion and do Ijtihad individually. Therefore this science is not associated with a particular class of the society; rather, it only depends on acquiring the necessary knowledge and intellectual skills. So if a Muslim is not capable of attaining such level of knowledge that would enable him/her to deduce religious laws for himself/herself, it is compulsory for them to refer to an expert who has specialized in this field, i.e., Mujtahid.

Mujtahids

A fully qualified religious expert (Mujtahid), who is supposed to study and deduce the practical laws of Islam according to the time requirements, needs to have specific features, the most significant of which are:

Being able to fully understand the Holy Quran and the other religious sources to discover practical laws from their origins.
Being equitable and trustworthy
Being capable of refraining from sins
Being able to keep away from earthly desires

It is also important to bear in mind that the religious experts (Mujtahids) do not ever issue a decree (Fatwa) unless they have found adequate and reliable proofs and evidence in the Quran, historical tradition (Sunnah), reason, and consensus; which is when they inform the people of God’s commandments.

Imitation (Taqlid) in Islam

Taqlid in Islam literally means "to follow or imitate someone" in the realm of religious do’s and don’ts or the religious laws one must obey. In Islamic terminology, it means to comply with the edicts of a religious expert (Mujtahid) regarding practical affairs of religion.  Broadly speaking, imitation is classified into four different categories among people:

An unlearned following another unlearned
A learned following an unlearned
A learned following another learned
An unlearned following a learned

Quran, however, mentions two of the above; “an unlearned following another unlearned,” which is strictly prohibited:

“For when they are told, "Come unto that which God has bestowed from on high, and unto the Apostle" - they answer, "Enough for us is that which we found our forefathers believing in and doing." Why, even though their forefathers knew nothing, and were devoid of all guidance?” (5:104)

And that of “an unlearned following a learned” (the focus of this article):

“Ask the People of the Book if you do not know” (21:7)

In Islamic thinking, the latter is the only acceptable kind of Taqlid in Islam that appeals to man's rationale. According to common sense, we follow the guidance of a religious expert (Mujtahid) who knows the laws of religion, just as we voluntarily conform to the advice of a doctor when we need medical attention, or in the same way, we consult lawyers and comply with their recommendations. It is inherent in man's nature to resort to experts in fields wherein he lacks expertise.

Practical matters of faith are no different. We, therefore, comply with an expert in the field of practical religious affairs too [3]. In this kind of Taqlid in Islam, which is permitted in Islam, two important elements are involved; firstly, the imitator (Muqallid) must completely trust and have confidence in the religious expert (Mujtahid). Secondly, imitation (Taqlid) must fulfill the imitator’s (Muqallid) demands and lead him/her to perfection. Clearly, this does not make sense in the other forms of imitation (Taqlid) but the last one.

In short, the religious concepts and teachings of Islam fit into two main parts; the axioms and the practical commandments (practical principles). As for the Islamic axioms, i.e., Monotheism (Tawhid), Prophethood (Nubuwwah), and Afterlife (Ma’ad), no one is allowed to imitate; instead, each person is supposed to investigate and accept them individually since they are regarded as the main entrance to the religion of Islam.

But about Practical principles, which are obligatory practical commandments, Muslims are encouraged to investigate and find them out as individuals if they are able to do so; obviously, they are not allowed to imitate anyone. If they are not capable, though, they have to follow religious experts (Mujtahid) who have become specialized in Islamic science fully and deeply.

It is learned in this article that the cases in which Taqlid in Islam or imitation is allowed, are very limited in Islam. In fact, it is possible for every single Muslim to step on the path of investigation to attain knowledge and awareness about the truth and commandments of Islam themselves.

Prayer in Islam (Salat) is one of the most important practical principles of Islam [1]. It is a physical, mental and spiritual act of worship consisting of prescribed actions and words. Every action in the prayer in Islam (Salat) is meaningful and if you want to know the Philosophy of Prayer in Islam,  we will see what each movement in the prayer means and represents.

The Philosophy of Prayer in Islam

Standing (Qiyam)

The prayer in Islam starts with standing. That is to appear in front of God gently and courtly with your whole heart and body; that is how one demonstrates the respect for others. Having the gaze down in Qiyam demonstrates the modesty towards God. It makes one forget about his\her superiority and helps to overcome his\her arrogance [2]. Also, knowing that one should stand five times a day in front of a superior power, who knows every overt and covert act and behavior, will eventually prevent from evil deeds and sins [2].    

Intention (Niyyah) of the Prayer in Islam

We do many things every day, some of which are repetitive and by habit, and we are not even aware of why we are doing them. Prayer in Islam, one of those works, seems to be a physical practice. That is why the prayer must have a Niyyah to prevent the prayer from becoming a daily habit and to help the Muslim to recall the reason behind that. Hence, a prayer without Niyyah will be a set of physical movements, and it won’t be accepted.  

Niyyah reminds one that he\she is showing up to demonstrate the submission to the divine orders. Having a pure intention in the prayer teaches to avoid duplicity. It is not necessary to repeat the words of the Niyyah. That is enough to recall it and to consider it throughout the prayer. Indeed, this should be considered during any other act or practice in daily life; firstly, to purify our intentions for God; then, to stick to that intention until the end.

Takbir   

The sayings in the prayer in Islam (Salat) start with Takbir. Takbir means to regard God as great. By saying Takbir, we express our belief that God is great. There exists nothing similar to Him. He cannot be perceived or touched by our physical senses and understanding [3]. Takbir reminds us of the Monotheism (Tawhid) which is the first pillar of Islam [4]. 

Bowing (Ruku)

Bowing (Ruku) is a perfect demonstration of the gratitude and respect that a human being has for God, as a divine source and a higher power. And, this is a unique posture that a Muslim will never have in front of anyone else [5]. In Ruku, every individual, in whatever position and grade, bows to God which consequently reduces the arrogance and pride within him\her. Lady Fatima (AS) said: “God has ordered […] the prayer to purify you from arrogance and pride” [6]. 

According to Imam Ali (AS), holding the neck straight during Ruku shows that one believes firmly in Islam such that he\she won’t give up even if he loses his\her life (to have the neck cut) for this belief. Another point in Ruku is that it is a unique posture that only exists in the Islamic ritual and distinguishes the Islamic prayer.   

Prostration (Sujood)

Prostration (Sujood) is exhibiting the maximum humility and dignity for God. Imam Sadiq (AS) describes that one is closest than ever to God in this posture [7]. According to the Quran: “to Allah prostrates whatever is in the heavens and whatever is on the earth of creatures…” (16:49). This means that in that posture, the human being is in harmony with the whole universe and creatures. 

Imam Ali (AS) explained that the first Sujood means that God has created us from the earth. Coming up from the first Sujood is the symbol of this worldly life. The second Sujood represents the death and returning to the earth. Finally, rising from the second Sujood symbolizes the afterlife [8]. According to the interpreters of the Quran, this refers to the fact that: “From the earth, We created you, and into it, We will return you, and from it, We will extract you another time” (20:55). 

The Prayer in Islam, Beneficial to Soul as Well as Body

There have been some attempts in the recent years to analyze and justify the physical benefits of performing the prayer. Those discussions might be true, but they are not the whole reason behind this practical principle of Islam. The prayer is a means of worship that engages the body and soul and is beneficial to both. The reasons above are a small part of the philosophy behind the acts of the prayer. One might refer to the advanced references for more details.
