Every day we meet several people at work, in the shops, at the university, in the neighborhood, or at parties and gatherings with whom we communicate and interact. Talking, telling jokes, shaking hands, touching or kissing usually happen in these interactions; but, is a Muslim allowed to do all these with whoever he/she wants? Or is he/she permitted to be exposed to such acts?  These and many similar questions are answered in Islam.

To clarify and form the relations among people, Islam has presented the concept of Maharim and the two categories “Mahram” and “non-Mahram” which sometimes serve as conditions, requirements, or the basis of several Islamic laws. Regarding the Islamic rules on marriage, these categories define who a person can and cannot marry. Likewise, when dealing with the Islamic dress code, i.e., explaining whom one must cover specific parts of a body in front of, the concept of Maharim is required.

Who is Mahram?

One’s Mahram is anyone whom it is permanently forbidden to marry because of blood ties, marriage ties or breastfeeding. However, a woman does not need to cover her hair and put on Hijab when she is in their presence.  A woman's male Mahrams fall into three categories plus her spouse [1]. Mahrams for a man are derived similarly. The Maharim for both, extracted from the verses of the Holy Quran (4:22-23) and (24:31), are listed below [1], and all other people and relatives are considered as non-Maharams.

Categories of Maharim

Permanent or blood Mahrams, with whom one is Mahram through blood ties:
parents, grandparents, and further ancestors;
siblings;
children, grandchildren, and further descendants;
siblings of parents, grandparents, and further ancestors (cousins and their children are not Mahram);
children and further descendants of siblings;
In-law Mahrams, with whom one becomes Mahram through marriage ties:
father-in-law, mother-in-law;
son-in-law, daughter-in-law;
stepfather (mother's husband) if their marriage is consummated, stepmother (father's wife) even if their marriage is not consummated;
stepson (husband's son) even if their marriage is not consummated, stepdaughter (wife's daughter) if their marriage is consummated[i];
Rada or "milk-suckling Mahrams," with whom one becomes Mahram because of being breastfed by her. When a woman breastfeeds an infant that is not her child for a certain amount of time under certain conditions, she becomes the child's rada mother and everything concerning blood Mahrams apply here, such as rada father/mother, rada sister/brother, rada aunt/uncle and so on. In English, these can be referred to as milk-brother, milk-mother, etc. [ii].

Maharim and Marriage

It is forbidden (Haram) to marry Mahrams, but one can marry non-Mahrams who have reached puberty. As explained above, Married couples are Mahram to each other. But unlike other Mahrams, the limitations and rulings on looking and touching do not apply to them; i.e., married couples are the only ones allowed to touch and look at the whole body of one another; even the private parts. 

Maharim and Social Interactions

Regarding social interactions, there are some rules according to the concept of Maharim:

Women and men are both required to keep their gazes downcast and should not stare at the other person when facing non-Mahrams or talk to them. Even Mahrams are not allowed to see certain parts of the body of each other (this will be discussed more under a separate topic “the Islamic rules on looking“);
When talking to non-Mahrams, the tone of voice should be serious, and the dialogues should be direct and as much as necessary. One should also avoid telling jokes and laughing loudly [iii];
Any physical contact (i.e., shaking hands, hugging touching) with non-Mahrams is forbidden (haram), except for curing patients. In this case, if a doctor of the same gender as the patient exists and can cure, then it is forbidden to refer to a non-Mahram doctor.
When being sole in a closed room (where no one else can enter, i.e., locked place), it is forbidden for a non-Mahram man to remain alone in the company of a non-Mahram woman. The Prophet of Islam (PBUH&HP) said: “No man is alone with a woman except that Satan is the third one present ” [2];
It is required (Wajib) to cover specific parts of a body in the presence of a non-Mahram according to the Islamic dress code. For men, this includes from navel to knee. For women, the clothing should cover their hair and body, but covering the face and the hands, from the wrist to the fingers, is not mandated [3].

Notes:
[i] sister-in-law and brother-in-law are not Mahram.

[ii] Refer to your source of emulation (Marja’ Taqlid) for more details and the rulings.

[iii] See the article on modesty.

We are far ahead of the time when people lived in actual social networks. People living in a town or village were in a strong relationship with one another, and of course, it served them well.
But, maybe people were too closely related back then. And it had its downsides, too. “Give me a break, please, I need some privacy!” That’s what we said to the social life of the past times. The modern way of life ascribed so much importance to our privacy. This, too, had its downsides and sometimes made us feel so lonely. It didn’t quench our need to see and be seen. We needed to share more.

An Exciting Invention… 

But, modern life and technology also had the answer to that. They provided an unaccountably cheap and easy way of making relationships, without the need for getting quite out of our private zone; virtual Social Networks!

Well, that’s great! We can get to know about our family and friends without spending much time or money. We can easily make thousands of friends from around the world. We can share our ideas and lifestyle with them and get to know about theirs. Like all other inventions, there are many good ways to benefit from social networks. And there being many good ways to benefit from something, is somehow equal to its lawfulness in Islam. 

“… who bids them to do what is right and forbids them from what is wrong, makes lawful to them all the good things and forbids them from all vicious things…” (7:157).

Social Networks in Islam: Rules Apply!

But is using social networks in Islam forbidden? Does Islam have any special resistance to these networks? Well, not really. And the rules on what we should do and what we should try to avoid are pretty much the same as the ones we need to observe in actual communications.

Therefore, as we are always careful to avoid any harm in our actual relationships [1], we should also do the same in these virtual sites of getting together, and try not to go for the bad things that might be found in there, nor spread things that might do more harm than good to others or to the society. 

That means even if it is a boy-girl or man-woman relationship, there is nothing wrong with it as long as it is an upright, righteous, and honest one, and as long as you observe modesty and the rules of covering, the same way as a relationship between men and women in the outer world.

Also, Islam very much calls us up to mind the circles we move in [2], which are, more or less, a representation of our character and inclinations! Do our friends and groups in social networks –as well as in the real world– help us and change us for better? Or that they are just fun for a short time and may bring us lasting sorrows and regrets? [3]

Slippery Road… Watch Your Steps!

You might have noticed that conventional social networks, being inherently so cheap and easy, tend to make everything cheap and easy in all respects… and maybe too much so sometimes!
Suppose you share a highly valuable and precious post on Facebook –which is the easiest way to share it, of course– and your friends would barely spend five seconds to look at it! 

We are in the habit of taking everything easy in these virtual places; even our relationships. We don’t care that much about what we see or share, and sometimes about the kind of relationships we are making, while, to the contrary, a Muslim is always required to be watchful of his or her doings! [4]

So, apart from the benefits of being cheap and easy for use, they also make it easier to lie, to pretend, or to do any wrong. We may not be quite conscious that some of our relationships in the social networks could be, more or less, a kind of betrayal of our wedlock! Or a little too open to be modest and righteous! For, according to Islam, a husband’s level of modesty affects that of his wife and vice versa. [5] That means, the more righteous a spouse, the more so will be the other! That’s why it is even more important here never to forget that, little as it may be, a wrongdoing is always wrong, whether in a virtual social network or out there in the real world. 

“So whoever does an atom’s weight of good will see it, and whoever does an atom’s weight of evil will see it.” (99:7,8)
