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.

Responsibility in Islam also covers every action that one is supposed to do as a Muslim and his/her interactions with others. Thus, human beings are responsible towards others including: whoever they interact with, whatever they have been given in this world, the divine duties they are expected to perform, and their surroundings and environment.

The responsibilities of a Muslim towards other human beings were discussed in the first part of the article. Here the focus is on the responsibilities towards some non-humans including divine duties [i] and, the property and belongings.

The Rights of Prayer as One's Responsibility in Islam

The right of the ritual prayer over one is to know that he\she is standing before God. Knowing that one should stand in His presence like a lowly servant who is inclined to approach his lord, and who is fearful and ashamed because of his\her sins, but still hopeful of His mercy [1], is our responsibility in Islam towards our prayers. 

He\she should also magnify Him through stillness, bowing of the head, humbleness of the limbs, yielding of the wing, and by saying the best supplications to Him. Then, one should beseech Him to save him\her from the punishments that he\she deserves for his\her faults and sins [1].

The Rights of Fasting

The right of fasting is to know it as a veil that God has set up over one’s tongue, hearing, and sight, private parts, and stomach, to protect him\her from the Fire. Whoever protects his\her parts of the body with the veil of fasting, can be hopeful to be saved from the punishments and the Fire.

But if one leaves his\her parts of the body to do freely unlawful (Haram) acts (e.g., looking at unlawful things and scenes that incite lust and encourage disobeying God) and does not fear God, he\she won’t be safe anymore [1]. 

The Rights of Pilgrimage

The right of pilgrimage is that one should know that he\she has immigrated from his\her sins to God and is standing in His presence. He\she should also know that it is through the pilgrimage that one’s repentance can be accepted and he\she performs an obligation made incumbent upon him\her by God [1].

The Rights of Charity

Of the rights of charity is to know that it is like storing away with God and is a deposit for which no witness is needed. Hence, it would be better to donate in private other than in public. Also, one should not remind others of what he\she has donated since the charity is like a saving whose benefit returns to the donor.

Otherwise, the same thing might happen to him\her when someone else does him\her a favor. Moreover, reminding others of the charity donated demonstrates the impure intention of the donor; like the tendency to show off or humiliate others [1].  

The rights of Sacrifice [ii]

Of the rights of the offering is to consider it as a way to expose oneself to God’s Mercy. So, one should make offering not for receiving others’ approval, but God’s approval.  Therefore, what others say about the offering should not matter [1].  

The Rights of Property

Of the rights of the belongings and property over one and one's responsibility in Islam towards them are to gain it through lawful (Halal) means, to spend it on lawful (Halal) purposes, and to utilize it such that it brings about blessing and salvation in this world and the Hereafter [1]. Imam Sadiq (AS) said that whoever makes money in unfair ways, he\she will lose it justly [2]. According to Surah Qasas, one should use the wealth that God has granted for doing good to others and preparing for the Hereafter (28:77). 

The property and wealth should be used to get God’s satisfaction. It is narrated from Prophet Muhammad (PBUH) that God will punish those who forget about the poor people among them and keep on raising money [3]. Hence, one should not prefer his\her belongings to his\her spirit such that he\she hesitate to use them for spiritual progression. Otherwise, others will inherit this property after his\her death. If they utilize the inherited property in unlawful (Haram) ways, he\she will also be punished for that. If the inheritors use the inherited property properly, they are the ones who will be rewarded [1].

[ii] Animal sacrifice for the sake of God.
