The Quranic point of view with 
regard to the institution of marriage is based on the following principles and 
laws:
Interdependence of man and woman in ensuring fullness of life for each other 
through mutual affection, mutual confidence and mutual protection, as husband 
and wife has been stressed by using a metaphor of profound beauty: "They are a 
garment unto you and you are a garment unto them" (2:187)
For those who can afford it, marriage is an obligation. The Quran says: "Marry 
those among you who are single, and the pious among your slaves, male or female: 
if they are in poverty, Allah will give them means out of His Grace: Allah is of 
ample means, and He is aware of all things." (24: 32)
Contrast it with the attitude of those religions, which advocate celibacy and 
idolize it as the ideal of perfection, considering sexual satisfaction even in 
the bond of marriage as a positive evil from the spiritual point of view. Thus, 
in Christianity: "As an institution, Jesus regards marriage as essentially 
physical and intended only for the present age. Those who were to share in the 
blessings of the eschatological kingdom would neither marry nor be given in 
marriage but would be possessed of the non-physical body in the resurrection." 
(*1).
It was this outlook on sex which led to the rule that no man or woman, married 
or unmarried, who had performed the sex act the previous night, should take part 
in a Church festival or in the Eucharist. (*2).
Christianity, writes the Sociologist Ludovici, "preaches that sex is to be 
deplored, to be avoided, and, if possible, negatived. And the Puritan, who may 
be regarded as the extreme Christian, is notorious for his implacable loathing 
of sex." (*3). 
Marriage is a social contract. The word Nikah, used for marriage in the Holy 
Quraan, originally means Aqd, according to Imam Raaghib Asfahaani (*4). (alaihir 
rahmah). Thus, the very word Nikah implies that marriage is a social contract, 
and not a sacrament, although it is a sacred contract. Moreover, the Quraanic 
permission to terminate the relation of marriage, if it becomes absolutely 
impossible for the husband and the wife to continue that relation, proves that 
the Quraan regards marriage as a social contract only.
Women are not to be treated as property (*5). The Quraan says: "O ye who 
believe! You are forbidden to inherit (as property) the women against their 
will." (4:19)
Marriage with persons of certain categories has been prohibited. The Holy Quraan 
has prohibited marriage with all those who may stand in the relations of 
consanguinity, or affinity, or fosterage. Almighty Allah states; "Forbidden to 
you are your mothers and your daughters and sisters and your father's sisters 
and mother's sisters and your brother's daughters and your sister's daughters, 
and your mothers who have such to you and your foster sisters and the mothers of 
your wives and daughters (your step-daughters) who are in your care from the 
wives with whom you had intercourse but if you had no intercourse with them, 
then there is no Haraam in their daughters, and the wives of your sons who are 
of your loins and to have two sisters together except what has already passed 
(*6). Undoubtedly, Allah is Forgiving, Merciful." (4: 23)
