Morality includes ethics or moral philosophy, and offers human beings the proper way to spend their lives. These etiquettes suggest the ideals and principles we should aim to achieve, morally commendable actions, and what is considered immoral. Religion may be described as a belief system that elevates people's lives and affirms the presence and ultimate dominance of a spiritual, supernatural, omnipotent divinity that transcends the material realities of day-to-day life. Ethical principles and religious tenets share some ground but do not correspond exactly. Most – but not all – faiths give their adherents ethical instruction. Much, but not all, moral philosophy has its origins or linkages in religious belief.

What do we mean when we refer to religion?

It is challenging to provide a specific definition of "religion" since the term "religion" is susceptible to various interpretations and understandings. On the other hand, religion may be seen as an organized body of ideas and rituals rooted in a common worldview.
This worldview often consists of a consensus on a set of moral principles and an understanding of the meaning of various religious texts. A feeling of connection and identity may also be provided to those who subscribe to a particular religion.
In addition, religion may be understood as the belief in and worship of a superhuman, governing authority, most prominently a personal deity  or gods. This is one comprehensive definition of religion. It is often connected with rites, and it may also entail the reading of holy books. 

What exactly is ethics?

The subject of how a person ought to conduct their life is at the center of the study of ethics, a subfield of philosophy. It seeks to give a framework for ethical decision-making by posing the question, "What is the proper thing to do in this specific situation?" and attempting to provide an answer.
Throughout the course of human history, a great variety of ethical theories have been proposed; nonetheless, no one response is universally accepted to all ethical concerns. Rather, various individuals are likely to arrive at different conclusions depending on the principles and ideals that are most important to them.
The ethical tradition significantly focuses on applying moral principles in everyday life. Instead of providing instruction on how to live a good life in the abstract, ethics aims to offer direction on how to live a decent life in the actual world.

Relation of Ethics to Religion

The history of the connection between religion and ethics may be told via how religion connects to applying practical experience and analytical thought to investigate morality. A significant number of people who participate in religious activities believe that they do not need to comprehend the rationale behind the moral teachings of their specific religion since all they need to know is what God considers morally acceptable. They are not concerned with the rationale behind why some actions are ethically commendable while others are disapproved by society. However, this rejection of critical thinking may impede persons who feel this way from properly knowing all of the particulars of their faith. 
Various perspectives exist on the relationship between religion and ethics, from the notion that religion is the ultimate cornerstone of ethics to the view that ethics is built on humanism principles justified primarily and often only by appealing to reason. These two extremes are often discussed in a manner that leaves little possibility for compromise or pragmatic answers to real-world problems; as the Prophet Muhammad says: " The best of you are those who have the most excellent morals."

The merciful religion of Islam

This presentation of Islam's ethical framework is made in the context of Shariah, the Islamic social and legal order. Whatever promotes one's or society's well-being is ethically desirable in Islam, whereas whatever causes harm is immoral. Islam's ethical framework is the bedrock of a society based on the religion's teachings, deemed divine and unchanging. Regarding personal relationships, business dealings, social gatherings, and public appearances, Muslims are expected to exercise extreme caution following Islamic ethics.

Who exactly is Muhammad?

Muhammad was born in Makkah in 570, while Christianity was still a relatively new religion in Western Europe. His parents had passed away before he was born, leaving him in the care of his revered Quraysh uncle. When he was older, people sought him out as an arbitrator because of his reputation for honesty, kindness, and sincerity. Historians have remarked on his equanimity and quiet demeanor.
Muhammad was a very pious man who had always disapproved of the corruption that pervaded his culture. Occasionally, he would go to the Cave of Hira, located on the slopes of Jabal al-Nur, also known as the "Mountain of Light," not far from Makkah, and meditate there.

Ethics Without Religion

Even if a significant amount of moral philosophy derives from religious belief, the history of secular ethics may be traced back to ancient times. Many philosophers throughout history have belonged to some religious belief system, and acknowledged that it is impossible to live a happy life outside the influence of religion. 

Both ethics and religion presume that the soul is immoral 

Similarly, ethics imposes the need that the soul to be eternal. Although human existence is brief and constrained, the ideal of ethics is vast and unbounded. It is unlikely that it will realize its potential in its limited lifetime. The only way to achieve one's ethical goal is to live an infinite number of lives in succession.
Single life cannot sate the unbridled need of a human being for the comprehension of truth, appreciation of beauty, and fulfillment of their potential. A person's moral behavior throughout life may show the soul's immortality.
In this manner, ethics and religion lead man along the paths of choice and emotion to the ultimate good, beauty, wisdom, and total perfection God is. Both are impressive to one another, and both are necessary for the growth of the human person.
Conclusion

There is a noticeable gap between religious beliefs and moral principles. ethics is grounded in the application of reason. In writing this article, we aimed to clarify the distinction and similarity between these two ideas.

One of the principles of Muslims (Shia Islam) is Imamate which means leadership and is a universal authority over people’s religious and worldly affairs. Imams are religious experts who are consciously and willingly infallible and perfect leaders who provide believers with Islamic teachings and laws to help them reach prosperity and perfection.

The Difference between Imams and Prophets

The followings are the differences between Imams and prophets:

The prophets have brought us the religion, its axioms, and God’s commandments using revelation they received from God, whereas Imams protect the religion against any kind of deviation or distortion and are responsible for the performance of God’s commandments.

In other words, prophets show us the right way towards the divine source, i.e., God, but Imams guide us through this path step by step until we reach it. Apart from the necessity that the Prophet’s path should be known, there have to be leaders (Imams) who are perfect themselves and can teach people and stimulate their energy to help them realize their full potential at any time.

The second difference is that prophets had direct communication with God, and God’s commands were revealed to them, but Imams have not been direct receivers of God’s message; rather, they got it from prophets, and at times, they were supposed to interpret and update that message.

However, whatever roles the prophets had, have been all transferred to Imams. Moreover, our major prophets were Imams, too; they were also responsible for the protection of God’s religion as well as performing His orders in the society and had significant roles in guiding people.

The Status of Leadreship

As mentioned above, not every prophet was Imam, nor did every one of them have the opportunity to expand and interpret the commandments they received from God.  There are two important examples of the greatest prophets that were also Imams; Prophet Muhammad (PBUH) and Prophet Abraham.

What the Quran says about Abraham is that he was tried by God with certain commandments which he fulfilled (2:124). His final test was to slay his son - Ishmael- who was born to him when he had reached his old age. After they both submitted to the command of God and Abraham showed his willingness to sacrifice all his belongings for Him, God asked him to stop, for He wanted to see his sheer submission, not sacrificing his son. So Abraham had passed the stages of prophethood and a lot of exams when he reached the status of Imamate and God appointed him as the leader of humanity:

“[Allah] said, I am making you the Imam of mankind ” (2:124).

This dignity was also given to our last prophet -Muhammad (PBUH) - who conveyed the message of God at the beginning of his mission and in the meantime he carried on teaching people and leading them to the right path.

The Necessity of Leadership

In the religion of Islam, Imamate is a position that is necessary according to the following rationales:

The Grace of God

According to Shia viewpoints, Imamate is proved to be the grace of God (Lutf), which is one of His attributes defined as ‘beneficence’ or ‘kindness’ that would help to bring His creatures nearer to His obedience and facilitate their moral rectitude. In fact, that is the grace of God that requires Him to appoint Imams to keep people away from God’s disobedience.

Protection of the Religion against Distortion

Training Talented Human Souls

People are different in obtaining awareness; some are capable of finding the right path, some are not; Imams help both groups to find their way through perfection.

Continuity of the Religion

23 years of preaching did not give Prophet Muhammad (PBUH) the opportunity to teach people Islamic laws, thoughts, and beliefs completely. So, there had to be perfect people, trained by the prophet to give humans all the Islamic teachings and to guarantee the endurance of religion.

Being Living Role Models for People to Follow

Strengthening the Rational Laws

Prophets are necessary to strengthen the rational knowledge of humans by their words. Although people can rationally understand the majority of realities about religious principles, there are still uncertainties in their hearts which can prevent them from carrying out such principles wholeheartedly.

However, when these rational perceptions are strengthened by prophetic words then all of these doubts and distrusts would be obliterated, and humans can approach their sacred goals. There are some affairs whereby the common sense of human beings cannot identify their advantages and disadvantages.

In such cases, people should resort to religious leaders to help them distinguish the good from what is not. Many things can be useful, and some others can be harmful. Before ascertaining which is which, human beings are not able to distinguish between the good and the bad purely by relying on their intellectual power. Consequently, they feel the need for someone who can clarify these qualities, and this is something which is only within the power of religious leaders who are connected to the divine through revelation [1].

Divine Wisdom   

God has a purpose for his actions, and since He is absolute perfection, the ultimate purpose of His divine action is creating the human being, and the aim of human creation is his perfection, the best example of whom are Imams. Furthermore, the human is the noblest of all creatures and Imams are the noblest of them who reach perfection before anyone else on earth. In other words, life, existence, knowledge, power, and beauty cannot be given to or obtained by the other creatures before they are manifested in perfect beings, Imams.

Leadership in the Quran

The importance of Imamate is clearly stated in this verse of the Quran:

“Today I have perfected your religion for you, and I have completed My blessing upon you, and I have approved Islam as your religion” (5:3).

Complete vs. Perfect

According to this verse, Imamate is what through which God has perfected His religion and completed His favor. Here we need to see the difference between perfect and complete:

The religion is considered complete only if it includes all the necessary constituent parts. Perfect versus incomplete, however, has a different meaning. A complete compound object can potentially turn to something it is capable of; that is one can change and pass through the stages of perfection until they reach it and as long as they have not attained that very last stage, they are still incomplete.

The Completion of the Religion

The religion of Islam gets completed when God’s commandments (favors) like praying (Salat), fasting (Sawm), Zakat, Khums, etc. are all sent to us. Imamate completes the religion, for it is the last favor sent to human.

The Perfection of the Religion

The perfection of Islam, though, concerns the truth of this religion, not the exoteric laws and commands. One cannot fully understand the reality of Islamic doctrines, i.e., monotheism (Tawhid), prophethood (Nubuwwah), the afterlife (Ma’ad), alone without Imams. Therefore, Imamate, the last stage of human evolution, improves the quality of faith without which the religion cannot reach its perfection.

Who are Imams?

As mentioned before, Imamate is the last grace of God upon us which has to exist so as to prove God’s perfection. This cannot be endowed unless Imams are infallible and therefore this status of them needs to be text-oriented; that is their selection by God is stated in Quran and Hadith and asserted by Prophet Muhammad (PBUH) and each of his twelve successors:

1. 'Ali ibn Abi Talib;
2. Hasan ibn 'Ali;
3. Husayn ibn 'Ali;
4. 'Ali ibn Husayn;
5. Muhammad ibn 'Ali;
6. Ja'far ibn Muhammad;
7. Musa ibn Ja'far;
8. 'Ali ibn Musa;
9. Muhammad ibn 'Ali;
10. 'Ali ibn Muhammad;
11. Hasan ibn 'Ali; and
12. al-Mahdi.

God has never left the earth devoid of an Imam; Imam Mahdi is our current Imam and the ultimate savior of humankind who has been living in occultation since 874 AD and will return with Christ to fill the earth with peace and justice.

Conclusion

So the concept of Imamate, rooted in the revelation of God, is approved in important verses of the Quran, and what’s more, it is rationally based on the reasons mentioned above. God has created humans to give them the opportunity to go through the right path to attain eternal bliss and perfection. That is why He has appointed for us infallible Imams as successors of the last prophet -Muhammad (PBUH) - to help us achieve this purpose.
