There is a consensus among almost all Islamic jurists according to which Muslim women are forbidden to marry non-Muslims. This is clearly stated in Surah Baqarah: “do not marry polytheistic men [to your women] until they believe. And a believing slave is better than a polytheist, even though he might please you” (2:221).

This prohibition applies to both temporary and permanent marriage. But what can be the wisdom behind this Islamic rule?

Choosing a Compatible Mate to Marry for Muslim Women

In many narrations (Hadiths) [1] and some verses of the Quran (2:221); (24:26), Muslims are advised to marry those who are equivalent to them. Being equivalent mostly means to be similar in faith and religion; however, it also includes being alike in culture, wealth, education, and family values. Right after stating the prohibition on the marriage with non-Muslims in Surah Baqarah (2:21), the reason behind this is uncovered (2:221).

In this kind of marriage, the Muslim will be most probably influenced by the polytheistic beliefs (which are in direct contradiction to Islamic teachings) of his/her partner. In such a condition, if the Muslim accepts those beliefs, he/she will be surely destined to enter Hell, and even if he/she remains Muslim, the conflicts between the couple will make their life a real Hell [2].

Then, for Muslim women, marrying a non-Muslim man (whether disbeliever (Kafir) or a believer in other Abrahamic religions) is undoubtedly against the divine guidelines and Islamic teachings, therefore, must be avoided.

Marriage Affects One’s Religious Life

As soon as one gets married, he/she is not fully independent anymore to decide for everything in life. Many habits and interests will be influenced by the preferences of one’s partner and even some of his/her beliefs. Getting married to a non-Muslim means to be seriously exposed day and night to the practices and beliefs of a religion other than Islam, or even to feed the mind with anti-religious thoughts.

This might in the first place hinder one from practicing Islam, then make him/her indifferent to Islamic beliefs and principles, and finally end in converting to a non-Muslim! And, women are more prone to this change: “You (Muslim men) are allowed to marry who doubt in their religious beliefs, but Muslim women are not; since the woman is influenced by her husband and he makes her follow his religion” [3].

Islam completes the teachings of the previous religions [4], therefore it does not allow Muslim women, who have taken the straight path with the help of divine guidance, to deviate and join disbelievers (Kafir) or the followers of other religions by getting married to a non-Muslim and consequently to be supervised by non-Muslims and depend upon them.

Fulfillment of the Wife’s Rights in a Marriage

Islam considers certain rights for the wife over her husband. Treating gently, keeping respect, helping in household chores, forgiving her major mistakes, and honoring her are the duties of a husband in Islam [5]. Besides, men are required to pay the marriage portion (Sedaq) and the living expenses (Nafaqah) to their spouses [5].

These rights will be most probably ignored in a marriage with a non-Muslim man of whether an Abrahamic religion or any other religions and this is another reason to ban Muslim women to marry non-Muslims.

Children’s Education and the Following Generations

To many children, fathers are heroes or at least good enough samples to follow in life. To some, fathers are only a member of the family. In any case, fathers play a predominant role in the education of children.

Hence, a non-Muslim father educates children based on his beliefs, and he surely affects the characteristics, attitudes, and religious beliefs of his children and more generally the following generations. This way, Muslim women married to non-Muslims might find their children disbelievers (Kafir) or followers of other religions, which will be really regretful.

Some Rulings …

The only way Muslim women might marry a non-Muslim man is that he converts to Islam before marriage.

If the formula (Nikah) of a marriage contract is pronounced before the conversion of the man, the marriage contract will be void. If the man converts after this void marriage, the formula (Nikah) still needs to be repeated since the man had not been Muslim during the previous formula (Nikah) [i].

Not getting married to a non-Muslim man is such important that if non-Muslim women (whether disbeliever (Kafir) or a believer in other Abrahamic religions) deliberately join Muslims or immigrates to Muslim communities, and if their faith is examined, It is forbidden (Haram) to send them back to their disbeliever family if they want to stay with Muslims. In this case, Muslim women are not any more lawful to their non-Muslim husband, his husband neither (60:10).

The term Hijab literally means a cover, curtain, or screen [1], and is generally associated with the Islamic rule regarding women covering certain parts of their body [i]. Considering this matter, one might face many questions and misunderstandings. Perhaps some of the fundamental and mostly asked questions are: “Is the concept of Hijab and the law of covering certain parts of the body for women limited to Islam?” and “Did such a concept make sense in the Abrahamic religions which existed before Islam?” One way of gaining a better understanding and a broader insight into this issue is through a detailed and accurate historical investigation of the characteristics and the treatment of Hijab in the Abrahamic religions of Judaism and Christianity.

Hijab in the Abrahamic Religions

1.Hijab & Judaism:

It seems that covering certain parts of the body and maintaining a modest demeanor for women in society was of much importance in Judaism. The manner of Shuaib [ii]’s daughters toward Moses, explicitly mentioned in the Holy Quran, can best illustrate the necessity of acting modestly in the society for women:

“When he arrived at the well of Midian, he found there a throng of people watering [their flocks], and he found, besides them, two women holding back [their flock]. He said, ‘What is your business?’ They said, ‘We do not water [our flock] until the shepherds have driven out [their flocks], and our father is an aged man.’ So he watered [their flock] for them. Then he withdrew toward the shade and said, ‘My Lord! I am indeed in need of any good You may send down to me!’ Then one of the two women approached him, walking bashfully [modestly]. She said, ‘Indeed my father invites you to pay you the wages for watering [our flock] for us.’ So when he came to him and recounted the story to him, he said, ‘Do not be afraid. You have been delivered from the wrongdoing lot’” (28:23-25).

Based on this account, it can be argued that at the time of Prophet Moses, women’s modest and demure behavior was regarded as praiseworthy and respectful and a sign of their high status and distinguished personality in the society.

Moreover, there are some verses in Torah that name different kinds of clothing -Burqa or a veil covering one’s face- used by women as a kind of Hijab. In the book of Genesis, for instance, as addressed to Judah’s bride we read:

“And she put off from her the garments of her widowhood, and covered herself with her veil, and wrapped herself, and sat in the entrance of Enaim, which is by the way to Timnah; for she saw that Shelah was grown up, and she was not given unto him to wife. When Judah saw her, he thought her to be a harlot; for she had covered her face” [38:14-15].

As Will Durant [iii] puts, a common tradition for women among Jewish tribes was to attend public places with head-covers. This practice had to be followed as a rule and transgression from it would bring some consequences including divorcing the woman without paying her marriage portion [2].

Appearing bare-headed and without any cover for women, in some societies -e.g., the Far East and Mesopotamia- was considered as the symbol of inferiority and the characteristics of lower social standings. Moreover, women regarded the act of uncovering their hair in front of public eyes as a huge humiliation, to the extent that this act was performed in punishing the women who were guilty of a crime. Also, according to some Rabbis, women’s attendance without a kind of Hijab in the religious ceremonies and rituals was strictly forbidden [3]. 

2. Hijab & Christianity:

From the chosen and highly respected women named in Islam, the Holy Quran directly mentions Blessed Mary, mother of Jesus Christ, the messenger of Christianity, as the embodiment of a chaste, modest, pure woman and a true believer in God. Her status is so high in Islam that one of the chapters of the Holy Quran has been given her name.

In addition, in many of the Christian paintings and portraits, the figure of the Virgin Mary has been depicted with a complete head-cover as well as a long loose dress. So, Christian women who follow their prophet’s mother and the laws of Christianity, have attempted to observe modesty and chastity in their social interactions. As Jurji Zaydan [iv] states: “If by Hijab we mean covering body, this practice was common before Islam and even before the emergence of Christianity and its effects still remain in the European societies.”

Furthermore, there is some textual evidence in the Bible that refers to this tradition and its necessity among Christian communities. In the Old Testament, the book of Genesis, it has been said:

“For she had said unto the servant, What man is this that walketh in the field to meet us? And the servant had said, It is my master: therefore she took a veil, and covered herself” [24:65].

And the need for head-covering in religious ceremonies has been emphasized by Saint Paul in the New Testament:

“Every man praying or prophesying with anything down over his head dishonors his head, but every woman praying or prophesying with her head uncovered dishonors her head—it is the same as if her head were shaven.  For if a woman will not be covered, then let her be shorn! But since it is disgraceful for a woman to be shorn or shaven, let her be covered. … Judge for yourselves: is it proper for a woman to pray to God with her head uncovered?” [Corinthians 11:2-16].

The rule of celibacy for Christian priests and nuns -approached slightly different in the three main Christian denominations including Catholicism, Protestantism, and Orthodoxy [v]- though not accepted in Islam, is primarily and originally established to avoid worldly temptations and practicing self-restraint and modesty.

Also, the special kind of dress worn by nuns in churches which covers most parts of their body shows the emphasis of Christianity on the necessity of appearing with appropriate and non-provocative clothing in society.

Moreover, considering the paintings that portray western aristocratic females, as well as the literature of the pre-twentieth-century, it can be realized that wearing a suitable and modest dress by women represented their higher social standing and evoked the respect of other members of the society.

Up until the end of the nineteenth century, wearing hats and using long and decent clothing was common for women. However, with the passage of time, this tradition went through changes, and gradually the religious beliefs, and divine teachings of Jesus Christ faded away from their lives [5].

Nevertheless, in some eastern catholic and orthodox churches such as the Russian Orthodox Church, women are required to wear a head-cover when entering the church for attending religious ceremonies [6]. In addition, in Continental Europe and North America, most women of the Christian denominations including Anglican [7], Baptist [8], Methodist [9], and Roman Catholic [10] use a kind of head-cover when participating the religious rituals inside the church.          

Conclusion

With a brief look at what has been said so far, it becomes evident that the religion of Islam was not the inventor of the Hijab, rather this tradition had existed and practiced in different forms among the followers of the two Abrahamic religions of Judaism and Christianity.

The parallels that one can find in the characteristics of the Hijab and the philosophy behind it in these three religions reveal the fact that in a way Islam has only modified and continued this tradition.  According to Islam, also, the practice of wearing a Hijab is essentially aimed to preserve the human value and dignity of women when interacting with men outside the family circle and to provide a secure environment where everyone, man or woman, can perform their tasks effectively and morally.

Moreover, the kind of Hijab that Islam defines for women is covering all parts of their body except their faces and hands [from wrists to fingers] through wearing a modest dress, similarly, as we have seen in the previous paragraphs, Jewish and Christian women covered their head and were encouraged to wear non-provocative clothes. So, Islam, the last and most perfect religion, revised the rules of the preceding religions and completed the teachings of the previous prophets by providing thorough and applicable instructions.

While “the majority of Protestants do not require celibacy as a condition of election to the clergy.” Catholics, on the other hand, believe that “Priests and Bishops must be celibate, with the exception of Eastern Rite Catholics and Anglican married clergy who subsequently convert to Catholicism. These groups are allowed to have married priests” [4].
