Marriage in Islam: Purpose and Principles

A look at marriage in Islamic teaching, drawn from the Quran and authentic hadith.

Islamic teaching frames marriage, nikah, as considerably more than a legal or social arrangement – the Quran describes it in terms scholars regularly point to as some of the most tender language used anywhere in the text, treating the bond between spouses as one of the signs of Allah’s existence rather than a purely worldly institution.

Tranquility, Love, and Mercy

Surah ar-Rum contains the verse most frequently cited on this subject: “And among His signs is that He created for you mates from among yourselves, that you may find tranquility in them, and He placed between you love and mercy” (30:21). Classical exegetes note the three distinct terms used here – sakinah, tranquility; mawaddah, love; and rahmah, mercy – as together describing a bond meant to combine emotional warmth with a steadier, more enduring form of care that persists even when feeling alone might waver.

Garments for One Another

Surah al-Baqarah describes spouses as garments for one another (2:187) – a metaphor classical scholars have unpacked in several directions: garments cover and protect, sit closest to the body of anyone, and provide both comfort and modesty, an image scholars read as capturing the intimacy, protection, and mutual concealment of each other’s faults that marriage is meant to provide.

Completing Half of One’s Religion

A hadith recorded by al-Bayhaqi has the Prophet Muhammad ﷺ teaching that when a person marries, they have completed half of their religion, and should fear Allah regarding the remaining half – language scholars read as pointing to marriage’s role in providing the stability, companionship, and lawful outlet for natural desires that make sustained religious discipline considerably more achievable than it would be otherwise.

Marriage as Half the Sunnah of the Prophet ﷺ

A hadith recorded by Ibn Majah has the Prophet ﷺ stating that marriage is from his sunnah, and whoever turns away from his sunnah is not of him – a statement scholars cite against strands of asceticism, present in some religious traditions, that treat celibacy as a higher spiritual state. Islamic teaching consistently positions marriage as the norm and the encouraged path, rather than a concession to those unable to achieve a more spiritually elevated single life.

A Foundation Built on Consent and Deliberation

Classical jurisprudence, drawing on hadith describing the Prophet ﷺ voiding a marriage a woman had not genuinely consented to, treats free, informed consent from both parties as a foundational requirement of a valid marriage contract, not a formality. Scholars pair this requirement with an emphasis on realistic expectations going in – a hadith recorded in Sahih Muslim has the Prophet ﷺ instructing that a man not resent his wife for one trait he dislikes, since another trait he is pleased with is likely to be found in her as well, framing marriage as a relationship built for accommodation and patience rather than one expected to arrive already free of any friction.

Choosing a Spouse: What the Prophet ﷺ Advised

A hadith recorded in Sahih al-Bukhari and Sahih Muslim has the Prophet ﷺ describing four qualities people typically consider when choosing whom to marry – wealth, lineage, beauty, and religious commitment – and instructing that religious commitment should be the deciding priority, warning otherwise that a person risks ruin. Scholars cite this hadith not as dismissing the other three factors entirely, since compatibility in background and mutual attraction are addressed elsewhere in Islamic teaching as legitimate considerations, but as establishing a clear order of priority when those factors come into tension with one another. A related hadith recorded by at-Tirmidhi and Ibn Majah instructs that when a person of sound religious commitment and good character proposes marriage, the proposal should not be delayed or refused on account of status or wealth alone, warning that doing so invites widespread corruption and discord in society – language classical scholars have read as a direct caution against allowing purely social or financial considerations to override the primary standard of character the Prophet ﷺ had already named.
