Dancing is a natural behavior in many cultures; a way of showing happiness or sometimes sadness. In a theory raised by me! the release of energy by moving our body is dancing. But in a theory raised by a scholar "dance refers to a rhythmic movement of the body, usually for entertainment" [1]. Now, let us take both of these definitions into consideration and see what kind of dancing in Islam is forbidden (Haram).

The General Ruling of Dancing in Islam

In the view of some Islamic scholars, it is not permissible for women to dance anywhere in any ceremony irrespective of whether it is a wedding or a birthday ceremony except for a woman's dancing for her husband.

In expanding the above ruling, it has been said that “there is no problem in dancing in itself. However, if dancing entails sexual excitation or committing a forbidden (Haram) act like listening to forbidden (Haram) music, or it is in the presence of non-mahram men, it is forbidden (Haram). And it does not make a difference as to the various types of music. Generally speaking, if dancing is done in a sexually exciting manner, and lead to the commission of a forbidden act, or involves a bad effect, or if it is happening in front of a non-Mahram it is forbidden (Haram)” [3].

If a woman dances for her husband or vice-versa, and the dancing is not accompanied by a forbidden (Haram) act, there is no problem in it [4].

Dancing in Mixed Parties

In mixed parties where men and women are sitting together, the dance of men or women in front of others is forbidden. Some think that it is OK if men dance in front of women. But in fact, it is forbidden (Haram) for a man to dance. Dance of women in front of men and any dancing which may entail a bad effect and arousal of sexual desires are forbidden (Haram). Playing music and listening to it is also unlawful (Haram) if it is done in a lahwi, enrapturing manner.

No matter if men or women who are dancing together or in front of others are of their unmarriageable kin (maḥrams) of the opposite sex. What is forbidden about dancing is general, i.e., regardless of whether it is done by a man, a woman, or in the presence of one’s marriageable kin (non-maḥram) or unmarriageable kin (maḥram) [5].

Women Dancing for Women in Small Parties, Friendly Gatherings, and Weddings

Dance of women for women is permitted (Halal) if it is not done in a sexually exciting manner and does not lead to the commission of a forbidden act, nor entails a bad effect. However, it is forbidden (Haram) to attend a dance party if it is considered as accepting the forbidden (Haram) act of others or leads to committing a forbidden (Haram) act. Otherwise, there is no harm in it. Dance of a woman for other women is forbidden if her husband does not allow her to do so. 

Some people think that the rulings of dancing do not apply to wedding parties as it is just one happy night. But there is no difference between a  wedding party and other occasions. Dancing with music is forbidden (Haram) [6].

In the case of wedding parties, the dance of women in front of women is not forbidden (Haram) under the conditions mentioned above.

Men Dancing for Men in Separate Parties or Weddings

As mentioned before, by obligatory caution, it is forbidden (Haram) for men to dance.

Dancing for fitness/ Aerobics and other sports with music

Here we discuss the point of releasing energy by moving the body. Is it forbidden (Haram)?

If the movements of the body do not meet the criteria of forbidden (Haram) dance, and if it is not accompanied by forbidden (Haram) music, there is no problem in dancing in private or in groups of women for fitness. However, we have to make sure that such dancing is not happening in front of CCTV cameras or filmed by people who may show it to non-mahrams.

Aerobics and other sports that are based on rhythmic music are permissible if the music is not forbidden (Haram). If music does not cause ecstasy, there is no objection to it. The duty-bound (mukallaf) himself should distinguish whether the music is lahwi or not [7].

Dance Teaching Centers

Establishing centers for teaching and promoting dancing goes against the objectives of the Islamic system and it is impermissible by obligatory caution [8].

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.
