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.

When my nephew was about two years old, he experienced his first meet up with a cockroach. My sister and I found him sitting very close to a cockroach, looking at it, smiling and enjoying his discovery. As soon as we saw the cockroach, we started screaming out of fear of the cockroach. In a way that the poor little kid ran away and started crying. From then on, whenever he saw a cockroach, his first reaction towards the poor insect was to start screaming and running away.

We, unwantedly, passed on our fear and hatred of the insect to that little kid. This hatred was shaped in us when we were kids and is passed on to next generations. Hostile actions are being shaped against cockroaches. Different poisons are made to destroy them. And still, they are the biggest enemies of people of some nation. The same story exists with British people and their spider enemies.

We never even start asking ourselves, if we can have a different attitude towards these insects. In our understanding, they are dirty, aggravating creatures that should be destroyed. Yet, it has happened to me to watch some well-made documentary films about insects. And think to myself why I am so ignorant and hostile towards these beautiful creatures of God.

Prejudice and Discrimination

Prejudice, as described in Merriam Webster dictionary, is a “preconceived judgment or opinion; an irrational attitude of hostility directed against an individual, a group, a race, or their supposed characteristics.” [1] Prejudice is usually based on ignorance. For example, using the following phrases: ‘all men, all women, all Christians, all Muslims, all uneducated people, all youths, all poor people, all rich people, all Americans, all Arabs, etc.’ are signs of having prejudice toward a specific gender, religion, social level, or nationality.

Prophet Muhammad (PBUH&HP) says: “Avoid prejudice, as it begins with ignorance and ends up in regression.” [2]

In this article, we are going to analyze prejudice in Islam. And find out how much the definition of Merriam Webster dictionary is compatible with Islam’s view towards prejudice.

What Leads to Prejudice in Islam?

Imam Ali (AS) states that one of the main reasons for prejudice is “ignorance”. He explains that “As for Satan, he felt proud over Adam because of his origin and taunted him about his creation since he said, "I am of fire while you are of clay." And in the same way “the rich among the prosperous communities have been feeling vanity because of their riches, as (Allah) said: And said they: "We are more (than you) in wealth and in children, and we shall not be chastised." (Qur'an, 34:35)” [3]

In the Arabic text, the word that is used for “vanity” is Al-asbiyyah and Al-Lijajah, which means prejudice in Islam. Indeed, most of the times it is vanity and pride that makes people think they are better than others. As a result, they classify people and discriminate between different groups of people.

Indecent Prejudices

Prejudice in the following cases is blamed according to Islamic teachings:

1. Race:

“Among His (Allah) signs is the creation of the heavens and the earth, and the difference of your languages and colors. There are indeed signs in that for those who know.” (30:22)

2. Social Class:

“Do not marry idolatresses until they embrace faith. A faithful slave girl is better than an idolatress, though she should impress you. And do not marry [your daughters] to idolaters until they embrace faith. A faithful slave is better than an idolater, though he should impress you.” (2: 221)

This verse emphasizes on the fact that the only thing that elevates people in the eyes of God and should be noticed in human classification is one’s faith and wariness of God. “Indeed the noblest of you in the sight of Allah is the most Godwary among you.” (49:13): unlike many people who may choose their spouse based on appearance, wealth, education, family lineage, etc.

3.Gender and Nationality:

“O mankind! Indeed, We created you from a male and a female and made you nations and tribes that you may identify yourselves with one another. Indeed the noblest of you in the sight of Allah is the most Godwary among you. Indeed Allah is all-knowing, all-aware.” (49: 13)

Do not Humiliate Each other!

As it is clear in the above verses, that differences in nationality, race, color, or social class should not make a group of people feel that they are superior to others and that they have the right to insult or assault them.

Since prejudice is followed by mocking, insulting and humiliating others, Allah clearly detains people of such acts; “O you who have faith! Let not any people ridicule another people: it may be that they are better than they are, nor let women [ridicule] women: it may be that they are better than they are. And do not defame one another, nor insult one another by [calling] nicknames. How evil are profane names subsequent to faith! As for those who are not penitent [of their past conduct]—such are the wrongdoers.” (49: 11) and He emphasizes that “Indeed the noblest of you in the sight of Allah is the most Godwary among you.” (49:13)

Is Prejudice in Islam Always a Negative Attitude?

From definitions that we usually read about prejudice, we may think that prejudice in Islam is always an indecent attitude. But, in Islamic teachings, prejudice is not always a negative manner. Rather, in some cases, it is known to be admirable.

As Imam Ali (AS) points out, people should have prejudice for “good qualities and in praise-worthy habits like the protection of the neighbor, the fulfillment of agreements, obedience to the virtuous, opposition to the haughty, extending generosity to others, abstention from rebellion, keeping aloof from blood-shed, doing justice to people, suppressing anger and avoiding trouble on the earth.” [4]

Conclusion

With what we have discussed so far, we realize that prejudice comes from ignorance. And every one of us may have a negative prejudice against some people. Simply because we do not bother to gain more knowledge about other people, other religions, other cultures, etc. If we try to know other humans better and try to put ourselves in their conditions and empathize with them, and do not judge them based on what we’ve heard about them, but expand our knowledge by the sufficient studies, then there is a chance that we can help each other in the way of growth and improvement.
