As a precursor to any explanation on this issue, we must first have a very clear understanding of the concept of marriage in Islam and most people in the world and find out why this question has arisen.

According to the Quran: "It is He [God] who created you from a single soul, and made from it its mate, that he might find comfort with her" (7:189)

Obviously, there are other requirements for a person to fulfill when they decide to get married but Quran names comfort before anything else; that is most probably because the fulfillment of all the other needs also leads to the ease of mind and inner peace.

More interestingly, however, it is not only the holy Quran that says getting married is for the purpose of comfort; having a quick search on the internet makes you realize how all people around the world marry mostly for this emotional purpose, as well:

“…there is an important but neglected positive aspect that explains why people voluntarily enter into commitments like marriage: it is a way of expressing your love and devotion to another person. Not the only way, of course, but a well-established and particularly declarative way…” [1].

Monogamy is the best form of Marriage in Islam

To fulfill this emotional need of a person, the only acceptable form of marriage which is agreed upon by almost all psychologists, and is also recommended by Islam is monogamy. It is within the monogamous type of marriage that all the equal rights of men and women are preserved.

The feelings of love, commitment, loyalty, security, trust, honor, and respect as well as many other benefits [2] can be fully achieved when one has only one spouse.

Why, then, Islam Permits Polygamy for Men?

The reason has been explained in a comprehensive article. Based on what is discussed there, nowhere in the Quran, you can find a verse that suggests or encourages polygamy among men to attain more pleasure or to satisfy their carnal desires; there are no positive or negative comments on this regular unlimited tradition of the Arab culture.

Instead, the holy Quran imposes restrictions upon it and introduces it as a remedy to a social problem, i.e., the excess number of women in need of marriage over marriageable men, like at the time of war, etc.

Why can’t women have multiple husbands and polyandry marriage?

Having discussed the concept of marriage in Islam and the limited law of polygamy which is introduced as an exception in case of special social needs, and nothing against the equality of men and women, do you still find the above question unanswered?

If yes, here are some reasons why polyandry is forbidden for women:

It destroys the family which is the foundation of a healthy society. It is usually NOT easy for a woman to perform her duties as a wife and a mother despite having several husbands.

It is against the nature of women and also inconsistent with men's innate desire for exclusivity and love for his wife and children [3].

It adversely affects women’s health, since women with multiple husbands are more prone to STDs.

It increases sterility among women which will result in population problems.

It may cause identification problems for the conceived child.

It may cause identification problems for the conceived child, which will ultimately lead to legal troubles.

These reasons may clearly show why polyandry is uncommon and frowned upon among Muslims and most people in the world. The Islamic point of view on this issue, however, can be summarized as: “Allah desires ease for you, and He does not desire hardship for you” (2:185), and Allah knows best what is good for you.

One of the motivations of those who convert to Islam may be marrying someone who is a Muslim. In Islam, marriage is a sacred and dear institution to Allah, and it plays a very crucial role in the formation of an ideal society. It is in fact, considered one of the greatest Divine blessings for responding to the natural instincts of human beings. However, according to the Islamic teachings, faith is the first quality to be considered in choosing a spouse.

A faithful and harmonious partner plays a crucial role in having a prosperous life. It is on this basis that the Quran, the Holy Prophet (PBUH&HP) and his Ahl al-Bayt (AS) have laid great emphasis on religion and well mannerism as necessary criteria for marriage.

Meanwhile, an important question that comes to mind is that, “can we convert to Islam for the sake of marriage or not?”

The Highest Goal of Islamic Marriage

Marriage is a natural necessity for every human being and several good outcomes such as procreation, sexual satisfaction, peace of mind, etc. are considered as the purposes of marriage. However, these could not be the ultimate goal of marriage in Islam as the non-Muslims can also achieve these, perhaps in better ways.

Humankind is not created solely to eat, drink, sleep, seek pleasure or act lustfully. Thus, the aim of marriage for a religious person should be a means of gaining proximity to Allah and avoiding sins. In this regards, a good and faithful partner assumes a vital role as he/she invites his/her partner to goodness, in the same way as a corrupt person would tempt his/her partner towards corruption. Islam has enjoined its adherents to consider religion and good manners as necessary criteria for the selection of their future partners on different occasions.

The Prophet (PBUH&HP) said: “If I were to bestow all the good of both worlds upon a Muslim, I would endow him with a humble heart; a tongue which continuously utters the praises of Allah; a body patient enough to withstand all calamities; and I would give him a pious spouse, who when he sees her becomes happy and protects his property as well as her own honour in his absence”.[1]

Convert to Islam for Marriage

In the Quran, it is said:

“Do not marry idolatresses until they embrace faith. A faithful slave girl is better than an idolatress, though she should impress you. And do not marry [your daughters] to idolaters until they embrace faith…” (2: 221)

From the above verse, it is clear that faith and religion is an uncompromised condition for marriage in Islam. It has explicitly prohibited marriage with the infidels except that they embrace Islam, as the statement “until they embrace faith” indicates. Thus, neither is the man allowed to marry an idolatress nor a Muslim woman is allowed to marry an idolater. However, there is a separate ruling [i] to the marriage with the people of the Book (i.e., Jews and Christians).

Meanwhile, following the Islamic jurisprudence, it is considered permissible for someone to convert to Islam for marriage, as there is not any religion hindrance on that, as far as it is based on the sincerity of intention and a strong determination to act by the Islamic teachings. Although such a conversion might not be the best idea, it might be a perfect chance to think more about converting to the real and true religion.

Conclusion

In Islam, faith and religion are crucial requirements to be considered in the choice of a future spouse. This is because the ultimate goal of a marriage is the everlasting salvation in this world and the Hereafter. And this cannot be achieved by marrying an idolatress or idolater. However, based on the verdicts of the Islamic jurists, it is acceptable to convert to Islam for the sake of marriage, so far as it is based on the sincerity of intention and a resolution to work in line with the teachings of the religion.

Note:
[i] Books on the Islamic jurisprudence or the official sites of the religious authorities should be consulted for details of the ruling.
