One of the significant aspects of responsibility in Islam is the responsibility towards ourselves and how we treat our bodies and souls. As discussed previously, every Muslim is responsible towards himself.

Since human beings owe their existence to their unique Creature, they should treat themselves as their Creator has commanded. The spiritual responsibilities of a human towards him\herself and some of the duties that one has towards his\her body were discussed in the previous part of this topic. Here, we continue the discussion on the rights of the parts of the body.

The Rights of the Eyes as Your Responsibility in Islam towards Yourself

The eyes are the means of insight and awakening of the heart. Imam Ali (AS) said that a faithful person looks to learn, but a hypocrite looks to amuse [1]. Thus, of the rights of the eyes and one's responsibility in Islam towards them is to lower the gaze from whatever that is unlawful (Haram) and not to look at everything and everywhere around, unless there is a lesson or advice behind [2]. According to Imam Ali (AS), whoever closes the eyes from Haram, his\her heart will be relieved [3].

The Rights of the Legs

The legs are the means to walk towards the right path and to overtake others in doing good deeds. Hence, of the rights of the legs over one and the responsibility in Islam towards them are not going towards what is unlawful (Haram) or what humiliates him\herself [2].

The Rights of the Hands

Of the rights of the hands are not to do what is unlawful (Haram) with them, otherwise one will be punished in the Hereafter for what has committed by his\her hands, and will be blamed by others in this world; not to prevent the hands from doing what God has commanded to; and, to allow the hands to seek what is beneficial and useful for one [2].

The Rights of the Stomach

Of the rights of the stomach are [2]:

To be careful about what you eat (80:24);
Not to eat what is unlawful (Haram), neither a little of it nor too much; 
Not to consider the stomach as a container and not to overeat while ignoring others who suffer from hunger; “eat and drink, but do not waste” (7:31);
To eat moderately even when eating lawful (Halal) foods because eating less is the key to good health [4]; 
Not to forget that overeating makes one bored and lazy and stops him\her from doing good deeds. According to Imam Ali (AS), to eat less enlightens the mind [5];
To remember that drinking too much will also cause indiscretion and absurdity; 

The Rights of the Private Parts

Of the rights of the private parts are to protect them from what is unlawful (Haram). To do so, one requires lowering the gaze since the eyes affect the heart and mind greatly. Also, one should frequently remember the death and the afterlife. He\she should always have a fear of the divine punishment and ask God to help him\her to protect his\her private parts from sins [2]. 

The Physical Rights of the Body as the Responsibility in Islam towards Oneself

Every human being is composed of a body and a soul. These two, together, help one to live a natural life. The health of the body is as important as the health of the soul. Devoting everything in life to prepare for the afterlife and depriving oneself of the God’s blessings in this world is blamed in Islam. In Surah Qasas verses 77, Muslims are advised to apply the capabilities and wealth that they have been given to do good deeds and to gain rewards for the afterlife.

But, they should also consider and benefit from the blessings of this world (28:77). Indeed, it is possible to consider both the physical needs as well as spiritual ones simultaneously. Although fulfilling the physical needs is known to be important in Islam, one should keep a balance in life and avoid being luxury-oriented. Otherwise, he\she will always be busy to increase his\her wealth, and this might force him\her to unlawful (Haram) ways of raising money.

Racism and ethnocentrism are closely linked to the sense of superiority that lies within every human being. This issue has a long history - as long as human life, and is still an ongoing behavior that causes serious problems among human beings.

Racism is an important issue that Islam has considered; the issue whose history dates back to nations existed long before the birth of Prophet Muhammad (PBUH&HP). This unequal treatment was so weaved into people’s lives which they didn’t even realized its vile nature. Prophet Muhammad (PBUH&HP), also, lived in a society where racism was very common. The situation became even harder when people started to follow the religion of Prophet Muhammad (PBUH&HP). That was when racism out of tribal prejudice was extended to segregation based on religion, and many people who followed Prophet Muhammad (PBUH&HP) were driven from their homes or hometowns. 

The specific conditions of the era in which Prophet Muhammad (PBUH&HP) lived, as well as the deep roots of this wrong attitude in the history of humankind, were the main reasons why Allah (SWT) makes many recommendations about racism in the Quran. The Prophet of Islam (PBUH&HP), also, worked really hard to clear the minds of people from tribal, religious, and any other types of racism.

What does the Quran and Prophet Muhammad (PBUH&HP) say about Racism?

During the Arab ignorance, privileges such as lineage, race, wealth, number of children, and affiliation with a powerful tribe were considered the criteria of superiority over others. The verses of the Quran indicate that the number of children and folks were so important to them that in some arguments they even went to a cemetery and started to count the number of their dead ones:

 “Rivalry [and vainglory] distracted you until you visited [even] the graves.” (102: 1-2) 

It should have been hard for people of that mindset to accept that their lineage, children, tribe and wealth is of no importance in the eyes of Prophet Muhammad (PBUH&HP). According to an account, he said, “All the people, from the past or at present, are as equal as a comb’s teeth; therefore neither Arabs are superior to non-Arabs, nor white people to blacks. You are only distinguished by your piety and righteousness” [1]. 

However, although the Quran was revealed in such an environment that was limited in various ways and had a limited connection with the world outside the island, and the issue of ethnicity, race, and tribal life prevailed in all its aspects, it did not take on such a color at all. Allah addresses people in the Quran using the following phrases: "O children of Adam," "O people," "O you who believe," or "O you who have faith." The Quran removed racial privileges in that racist environment, and with the beautiful logic of "you are all children of man and were created from one parent," Allah declared them all brothers and sisters belonging to the same family:

“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 God wary among you. Indeed Allah is all-knowing, all aware.” (49:13)

As the verse above implies, One’s character and status are only measured by the level of submission to Allah and following His commands, not social or financial conditions. 

Religious Discrimination 

Apart from racism based on lineage, race, wealth, etc. people before and at the time of Prophet Muhammad (PBUH&HP) believed that religious beliefs gave them superiority over others. 

Based on that belief, people of different faiths were always conflicting with each other, instead of having sound arguments about different issues. Therefore, religious discriminations had been severely condemned by Islam, emphasizing that belonging to the followers of religion does not make people good or bad. But, it is their actions and their level of obedience toward Allah that give them superiority: 

“The Jews say, ‘The Christians stand on nothing,’ and the Christians say, ‘The Jews stand on nothing,’ though they follow the [same] Book. So said those who had no knowledge, [words] similar to what they say. Allah will judge between them on the Day of Resurrection concerning that about which they used to differ.” (2: 113)

The Quran on sexism 

The issue of fairness and justice among human beings is so important in Islam that the Quran has taken care of all different aspects in which people may act unjustly toward each other. Apart from racial issues that have been ongoing for ages, the issue of undermining and suppressing women in different domestic and social aspects, and depriving them of their rights had been a challenging issue in most parts of the world. 
The Quran condemns this segregation and states that men and women are equal in the eyes of Allah: 

“Whoever acts righteously, [whether] male or female, should he be faithful, We shall revive him with a good life and pay them their reward by the best of what they used to do.” (16:97)

Also, the necessity of observing women’s rights had been emphasized in many narrations from Prophet Muhammad (PBUH&HP) and his progeny. Imam Ali (AS), says in an account, “Women are Allah’s trusts upon you, do not hurt them, and do not put pressure on them” [2]. Therefore, men should be careful with their manners in treating women whether in family or in society. 

To conclude, the only thing that gives superiority to people is their piety and faith. Looking at the issue like this makes people closer to each other and all differences in color, race, ethnicity, shape, wealth, etc. create no distance between people. People gather around based on their spiritual interests and try not to judge each other, since the only one who is aware of the most faithful is Allah (SWT): 
“… And be wary of Allah. Indeed Allah knows best what is in the hearts.” (5: 7).
