Nowadays, we hear every day that our earth is becoming more and more polluted and that a day will come that our life on this planet will be no longer possible. This is undoubtedly the result of our negligence toward the blessing that God had granted us, the blessing of nature and a clean environment: “It is He who created for you all that is in the earth…” (2:29). We are responsible for whatever is going on in our surroundings and at the same time dependent upon it to be able to live.

It is important to note that at the time of the emergence of Islam, people did not face such complex environmental issues and thus this matter has not been dealt with in depth in Islam. Nevertheless, Islam has emphasized the significance of preserving the environment and provided us with guidelines that help us find solutions for such complexities through the narrations and actions of Prophet Muhammad (PBUH&HP) as well as the twelve infallible leaders (AS). This article is an attempt to summarize these matters for you briefly.

Why should we preserve the environment?

The answer is quite simple, and it reveals the direct correlation between human beings and their surroundings. Preserving the environment equals our own physical and mental wellbeing. Our immediate surrounding is where we are always in touch with, and its quality will inevitably affect our mind and soul. Moreover, we are the ones who make use of the environment to fulfill our needs, and the way we use it will ultimately determine our condition of life.

On the other hand, Allah has made this world in perfect equilibrium and human’s excessive exploitation of natural resources will result in damaging this balance: “And We spread out the earth and cast in it firm mountains, and We grew in it every kind of balanced thing” (15:19). When the balance is disturbed, the result will be the many environmental crises that we are faced with nowadays. These include pollution, global warming, natural resource depletion, waste disposal, climate change, loss of biodiversity, deforestation, ocean acidification, ozone layer depletion, acid rain, water pollution, etc. [1].

How Can We Preserve the Environment?

The problems mentioned above are the result of our irresponsibility toward the blessing of the environment, and this is we that should compensate for it. What follows are some Islamic guidelines for us to observe in our treatment of the environment:

1. Avoid Wastefulness

When you make excessive use of natural resources such as water or what is produced by water such as electricity, the paper that is made through cutting trees, fossil fuels, etc., you put the environment in danger and threaten its durability. Quran also emphasizes the necessity to be moderate in using God’s blessings in this world: “… Eat and drink, but do not waste; indeed, He does not like the wasteful” (7:31).

Moreover, our environment is not restricted to our use only but is a public possession from which every human being has the right to benefit. Therefore, we should be careful not to violate other people’s rights in having a share in the environment through our extravagant exploitation of its resources.

There is a general rule in Islam that bids Muslims not to “cause harm or return harm” [2], meaning that they should act in a way that neither brings inconvenience for others nor undermines their situation. Through wastefulness we bring injustice to both ourselves and other human beings; we consume their share in the environment and damage God’s blessing that was given to us to sustain our livelihood. So, respect yourself as well as your fellow human beings through respecting your surroundings. 

2. Keep your Environment Clean

Think about the environment as your home and keep it clean as you like your home to be neat and tidy. Prophet Muhammad (PBUH&HP) says in a narration that: “Allah is pure and likes purity and cleanliness… therefore, keep where you live in clean” [3]. As it was mentioned above, pollution is one of the most pervasive environmental issues in today’s world; this includes air pollution, water pollution, as well as the excessive amount of waste produced on a daily basis.

Those who have faith in Allah and consider His satisfaction in every instance of their lives must be much more cautious regarding their own or their environment’s cleanliness since as Prophet Muhammad (PBUH&HP) puts: “Cleanliness roots in one’s faith” [4].

Air, water, and soil are the three elements that are the source of life on the earth, which has been mentioned in the Quran as well as narrations [i]&[ii]. It is all the matter of your choice. Keep the air you breathe in clean by choosing to take a walk or public transportation instead of using your car. Preserve the water fresh and pure by avoiding throwing waste in the water, urinating in it, and producing waste water excessively; Imam Ali (AS) emphasizes that water has some inhabitants, so we should not harm them through polluting it [6].

Even at the time of war, Prophet Muhammad (PBUH&HP) forbade his soldiers to pollute or poison their adversary’s city [7]. So, let the soil from which your food is provided remain unpolluted by not throwing waste, especially those that do not dissolve in the environment such as plastic waste, etc.

3. Engage in Green Activities

Plant a tree or bring awareness to people about the environment and the natural crisis that is threatening the earth and its inhabitants. There are many narrations from Prophet Muhammad (PBUH&HP) that highlight the necessity of planting trees. For instance, he says: “If a Muslim plants a tree and a bird, human or another creature eats its fruit, it will be considered as an act of charity from him [by Allah]” [8].

Also, Imam Sadiq (AS) considers planting trees and agriculture as the occupations which bring lawful (Halal) earning for the person performing them [9]. When your surrounding is green, your life will become lively and energetic [iii], and you will become more efficient in your performance.

Conclusion:

Finally, it all depends on you and how you want your future to be like. A green and lively environment is the result of our endeavors to preserve it and to give our posterity the opportunity to enjoy the blessing of God. The message of Islam in this matter is again that of moderation and responsibility which guides human beings to live in perfect equilibrium with the environment.

[ii] Imam Sadeq (AS) said: “life in a land where is devoid of these three essential factors is highly difficult and challenging: clean air, fresh and plentiful water, as well as fertile ground” [5]. 

[iii] Imam Ali (AS) said: “looking at the green nature causes freshness, liveliness and vitality” [10].

The Cambridge dictionary defines wisdom as using knowledge and experience to make good decisions and judgments. (1) The most similar equivalent for this word in Arabic is the word  “حکمة” (“Hikmah”) which denotes justice, knowledge and tolerance. (2) 

This word has been used so many times in the holy Quran and has a special meaning in  Islamic literature. The holy Quran says:
Allah grants wisdom to whomever He wishes, and he, who is given wisdom, is certainly given an abundant good, and none takes admonition except those who possess intellect. (2:269) 
About this verse of the Quran, Imam Sadiq (AS) says:
(In this verse) Allah The Almighty has portrayed the intellectuals in the best way. (3)

Hikmah is the message of the Prophets

Allah The Almighty has rapidly pointed out this fact that He has sent the prophets with “Hikmah” and they should teach people how to be wise. The holy Quran says:

Allah certainly favored the faithful when He raised up among them an apostle from among themselves to recite to them His signs (the verses of Quran) and to purify them and teach them the Book and wisdom, and earlier they had indeed been in manifest error. (3:164)
And:
There have already come to them, reports (via the Prophets) containing admonishment, [and representing] far-reaching wisdom; but warnings are of no avail! (4:54)
Also: 
Invite to the way of your Lord with wisdom and good advice and dispute with them in a manner which is the best manner.. (16:125)
And: 
When Jesus brought those manifest proofs, he said, ‘I have certainly brought you wisdom, and [I have come] to make clear to you some of the things that you differ about, so be wary of Allah and obey me. (43:63)

Allah almighty even says that the holy Quran is a book full of wisdom:
These are among [precepts] that your Lord has revealed to you of wisdom. (17:39)
These are the signs of the wise Book (31:2)

What is wisdom in the eyes of Allah?

The original meaning of the word “Hikmah” is wisdom, knowledge and tolerance and the ability to use your knowledge in the best way; but Allah The Almighty prefers some special kinds of wisdom. The verses of the Quran and the hadiths, try to clarify the true meaning of wisdom from Islamic sight.

Obedience towards Allah 

•    Abu-Basir, one of the brilliant pupils of Imam Sadiq (AS) once asked him about the verse; “He grants wisdom to whomever He wishes (2:269)”. Imam Sadiq (AS) replied, “That (Wisdom) is obeying Allah and knowledge about Islam” (4)
•    Imam Baqir (AS) also says that “Hikmah” means: “not to commit the sins that Allah has ordained for it the Hell as a punishment” (5)
•    Once Prophet Muhammad (PBUH & HP) asked a group of people who they are.
They said that they are some faithful people.
The Prophet (PBUH & HP) asked: “What are the signs of your faith?”
They said: “We are content about what Allah has planned for us and we are submissive to the order of our God and we trust in him for everything.”
The Prophet said: “You are so knowledgeable and wise the way that your wisdom can almost make you like prophets.” (6)

Knowing our Imams

Imam Sadiq (AS) about the verse “…and he, who is given wisdom, is certainly given an abundant good (2:269)” said ,“The abundant good is knowing Imam Ali (AS) and the other Imams (AS)” (7) 
He also said: “(The “Hikmah” mentioned in the verse is) obeying Allah and knowing the Imam (of your time)”
In Arabic, the word “جهل” (Jahl) means “Ignorance”, which can be considered the opposite of “Hikmah”. So anyone who is not “Hakim” (wise) is “Ignorant” in Islamic culture. There is a hadith narrated from the Prophet (PBUH & HP) in which he said:

Anyone who dies while they don’t have an Imam will have died like a person in the ages of ignorance (8)

This hadith has been narrated by all Muslims’ Sunnis and Shiites and the authenticity of this record is undeniable. 
About knowing the Imam, Imam Sadiq (AS) also said:
Anyone from among the followers of Prophet Muhammad (PBUH & HP) who understands the status and the rights of their Imam, will find how delightful  having faith is.(9)

Understanding Religion

The last meaning of “Hikmah” mentioned in the Hadiths is “Fiqh” (jurisprudence) which means “Understanding”. In Islamic culture, this word is  employed  to define a deep understanding of religion and profound knowledge about  it . (10)
Imam Sadiq (AS) said: 

“Hikmah is the knowledge about religion and understanding it (Fiqh). Therefore, anyone who understands the teachings of the religion is a “Hakim” (a wise person). Indeed above all, Satan wishes the ones who deeply understand religion, to be dead.” (11)
The Holy Prophet (PBUH & HP) said: 
Allah has given me the Quran and he also gave me Hikmah just like the Quran and every house which therein is no Hikmah is nothing but a ruined place. So learn Fiqh and get to know the religion so that you don’t die like ignorant people. (12)

To wrap up, in the Islamic view, “wisdom” means knowing how to live as a good servant of Allah and living the same way. As you see, all the meanings mentioned in the Quran and the Hadiths are about knowledge of religion and living the way religion indicates. Knowing your Imam (who is the leader Allah has chosen for you) is the best way to understand what you should do and how you should obey the orders of Allah.  It is then obvious that all these different meanings and teachings employ a common concept which is obeying the order of Allah after having enough knowledge about it.  
It is then obvious that all these different meanings and teachings employ a common concept; obeying the orders of Allah after gaining and enjoying competent knowledge about them.
