One of the significant parts of responsibility in Islam is our responsibilities towards other people in our lives. Human beings are social creatures. Being in the society, humans are no more obliged to provide all their basic needs on their own. They might benefit from the skills of other people in various fields.

And in return, every individual should do something for what he\she gains from others. It means that everyone is responsible towards other people in the society. Being emphasized in Islamic teachings, it is over every Muslim to respect the rights of other people with the priority given respectively to his\her nuclear family, relatives, neighbors, other Muslims and other human beings [1]. 

The Rights of the Family as the Primary Responsibility in Islam towards Others

Family as the basic unit of the society is the first community where one’s social interactions begin. The support and peace that one receives in the family make him\her responsible towards them. Thus, the concept of responsibility in Islam towards other begins with our duty towards our family.  

Responsibilities towards Parents 

The rights that parents have over children have been discussed in another article, but briefly, they include:

Obedience to parents as far as it is not against God’s orders or unjust. Even in those cases, one should respect his\her parents [i],;
Having deep respect and great affection for them; 
Being humble, using a gentle voice and kind words when talking to them;
Praying and asking mercy for them (17:24), whether they are alive or not;
Offering father the property, honor, and life [2];
The rights of the mother are superior to those of father [3] such that they can never be returned unless with divine providence.

The Responsibility in Islam towards the Wife

A detailed review of husbands’ duties was presented in another article. These duties can be summarized as:

Paying the marriage portion (Sedaq);
Paying for the living expenses of the wife (Nafaqah) [4];
Paying wife for the house chores if she asks for [ii], [5];
Treating the family well, including wife;
Helping the wife in house chores [6];
Ignoring minor errors of wife and forgiving her major mistakes.

The Responsibility in Islam towards the Husband

The rights of the husband over his wife have been fully discussed before. Briefly: 

Husband as the manager of the family is the only person who is fully responsible for all affairs of the family. Accordingly, every member of the family should obey him;
Wife as the source of peace and solace to the husband (30:21) has to submit herself to her husband except during menstruation sexually [iii].

Responsibilities towards Children

The rights of children over parents begin before the conception and continue a lifetime. These rights already discussed in previous articles, can be summarized as:

Great care for the act of conception emphasized in Islamic teachings, which are important for the physical, mental and spiritual health of the child in the future;
Providing the necessary care for mother during the pregnancy to give birth to a healthy baby;
Reciting the Call to Prayer in the ears of the newborn];
Giving the baby a proper name at birth;
Breastfeeding the baby until the approximate age of two [7]; 
Behave the children nicely and respectfully;
Gradually familiarizing the children with religion after the age of Three [8];
Starting necessary religious education and guidance in belief and act during middle childhood;
Providing academic education at school; 
Teaching them moral characteristics and attributes;
Helping the children to perceive the physical and emotional changes of puberty to experience a pleasant transition during this period;
Allowing children to participate in every decision-making in the family when they are adults. 
Preparing the children for the responsibilities of married life at the age of marriage, helping them to choose a proper mate for themselves, and providing them with some of the basic needs of a small family. 

Responsibilities towards Brothers [iv]

Imam Ali (AS) addresses Malik Al-Ashtar in a letter and explains that “people are either your religious brother or they are humans just like you. They might make mistakes deliberately or unintentionally, as you do. Hence, forgive them just as you hope God to forgive you”. Imam Sajjad (AS) also enumerates the rights of brothers over each other [4]:

You should consider your brother as a powerful hand which is ready to help, a refuge in case of troubles, and a power upon whom you can always rely;
You should not take your brother as a weapon with which to disobey God, nor as a means by which to violate God's rights; 
You should never forget to help your brother against his\her self-incitement and to support him\her against his\her enemies; 
You should offer your brother wise counsel and should never leave him\her alone in case of need. However, if your brother does not obey God’s commands, you have to prefer God’s satisfaction with his\hers. 

Notes: 
[i] For more information, see ref. [3].
[ii] However, some of these rights depend on how the wife respects her husband’s rights.
[iii] Much care is also paid to the sexual needs of wives in Islamic teachings, and there exist enough instructions on how to satisfy them.
[iv] The term “brother” here is not confined to siblings; it also refers to every two or more companions of the same religion.

Imam Sadiq (AS) is the sixth Shiite Imam after his father Imam Baqir (AS). The Shiite school is mostly famous as “Jafari School” because Imam Sadiq (AS) played the most important role among the other Imams in explaining and spreading the Shiite teachings. Most of the Shiite hadiths are narrated from Imam Sadiq (AS). 

Enlightening people about the essential message of Islam

Some Islamic teachings and practices are considered as the outer aspect of Islam, like praying, Hajj, Zakkat and stuff like that. These are the practices which any Muslim should do and respect but all of them have a deeper meaning and a concealed message that people mostly do not get. Sometimes people get so much used to do these practices and conduct ceremonies that they forget about the original meaning of them. 
The holy Prophet (PBUH & HP) says: 
O Aba-Zar! (One of the companions of the Prophet) Allah almighty doesn’t care about your faces or your wealth, but he cares about your hearts and your actions (1)
When you pray or pay your Zakkat, it must change you and teach you that praying is for getting closer to Allah and Zakkat is for helping the needy. 
In this regard the holy Quran says:
Did you see him who denies the Religion?  That is the one, who drives away the orphan, and does not urge the feeding of the needy.  Woe to those who pray but are heedless of their prayers —who show off but deny aid. (The Holy Quran 107:1-7)
Imam Sadiq (AS) in different prayers says that if you pray but still feel pride and vanity, it will be useless for you because the Satan himself prayed for Allah for 6000 years but due to his vanity and jealousy, he couldn’t stand the greatness of Adam and tried to deceive him and Allah cursed the Satan. 

Being Kind with the ones who disagree 

Once Mufazzal ibn Umar (One of the brilliant pupils of the Imam) was sitting in the Mosque of the Prophet (PBUH & HP) in Medina. Then he saw Ibn Abi al-Ouja (one of the Atheist Philosophers) who was insulting the Prophet in the mosque and telling lies to the people saying that there is no god. 
Mufazzal says that this made him so angry and he couldn’t control himself so he shouted: “O enemy of Allah! Have you become atheist and denied the God who created you?”
Ibn Abi al-Ouja replied: “If you are one of the religious scholars, I will have debate with you and if you are not, our discussion will be in vain. But if you are one of the companions of Jafar ibn Muhammad (Imam Sadiq) you must know that he wouldn’t talk to us like that and he wouldn’t have discussion with us in this way. He has heard so many more disgraceful words from us but he never has insulted us. He is so knowledgeable, patient and wise and he wouldn’t lose his control out of anger, ignorance or animosity. He always listens to us.” (2)
Imam Sadiq (AS) is famous for his numerous debates with the Sunnis, Atheists, Jews, Christians and so forth, but he would never insult them. He always would order his followers to be kind with the people. 
For example about the Sunnis Imam Sadiq (AS) says:
Participate in their funerals and visit them when they are sick, and give them their rights because if a person among you is pious, honest, trustable and good-tempered, people would say “this is a follower of Jafar” and this makes me happy! (3)

Imam Sadiq (AS) and Caring about the young people

Once Imam Sadiq (AS) asked one of his pupils who had gone to Basrah (a city in Iraq):
“How was the enthusiasm of the people for our message and converting to Shia?” Imam Sadiq (AS) asked.
He said: “The ones who want to listen to our message are so few. Some of them did but they are few”
Imam Sadiq (AS) said: “You must talk to the young ones, because they are more eager for finding everything good.” (4)
Imam Sadiq (AS) also says:
“Teach hadiths to your young children from their childhood before the time that others beat you in training them” (5)
Young Shias must set Imam Sadiq (AS) as a pattern for themselves and follow him. They should learn more and more so that the different people who have gone astray can’t deceive them.
