Kafa'ah (compatibility) in marriage

1The meaning of kafa'ah

Linguistically, kafa'ah means being equal or matched. As a fiqh term, it is the husband's equality with the wife in certain elements which, if absent, are considered liable to lower the dignity of the woman or her wali and to threaten the harmony of the household.

• Kafa'ah is measured in the man: the man must be a suitable match for the woman. The woman is not required to be a match for the man — a man may marry a woman of lower standing.
• Kafa'ah is assessed at the time of the contract. Changes after the contract (for example, the husband becoming poor) do not annul the marriage.
• Its purpose is to protect women, not to perpetuate caste. Islam affirms: "Indeed, the most noble of you in the sight of Allah is the most God-conscious of you" (Surah al-Hujurat 49:13).

2Evidence and basis

The Prophet ﷺ said: "When someone whose religion and character you are pleased with comes to you (to propose), then marry him. If you do not, there will be tribulation on earth and great corruption." (Sunan at-Tirmidhi 1084, from Abu Hurairah; graded hasan with the support of other narrations, including the narration of Abu Hatim al-Muzani in Sunan at-Tirmidhi).

The Prophet ﷺ also said: "A woman is married for four things: her wealth, her lineage, her beauty and her religion. Choose the one who is religious, and you will prosper." (Sahih al-Bukhari 5090; Sahih Muslim, Kitab ar-Radha').

The Sirah shows marriages across status: Zaid bin Harithah (a former slave) married Zainab bint Jahsy of the Quraisy (see Surah al-Ahzab 33:36–37), and Fatimah bint Qais of the Quraisy was advised to marry Usamah bin Zaid (Sahih Muslim, Kitab at-Talaq). This is the basis for treating kafa'ah as a right that can be waived, not an absolute bar.

3Elements of kafa'ah according to the four schools

All schools agree that religion is an element of kafa'ah — a sinful (fasiq) man is not a match for a righteous woman. They differ on the other elements:

4The rights of the woman and the wali

According to the majority (Hanafi, Maliki, Shafi'i and the authoritative Hanbali view), kafa'ah is a binding condition (syarat lazim), not a condition of validity. It is a right shared by the woman and her wali:

• Shafi'i: if the woman and all the walis of equal rank consent to a man who is not her equal, the marriage is valid. If a compelling wali (wali mujbir) marries his virgin daughter to a man who is not her equal without her consent, the marriage is not valid according to the more apparent view (azhar). The wali hakim may not marry a woman to a man who is not her equal.
• Hanafi: an adult woman may contract her own marriage; but if it is with a man who is not her equal (kufu), the agnatic ('asabah) wali is entitled to ask the qadi to dissolve the marriage so long as the woman has not become pregnant or given birth. Later Hanafi scholars gave fatwa according to al-Hasan's narration from Abu Hanifah that such a marriage is not valid at all if she has a wali who does not consent.
• Maliki: kafa'ah in religion is a right the wali may not disregard; other aspects of equality can be waived with the agreement of the woman and the wali.
• Hanbali: there is one narration from Imam Ahmad that kafa'ah is a condition of validity; the authoritative view of the school is that it is a binding condition that can be waived.

Conversely, if the man is a suitable match and the woman chooses him, the wali may not refuse without a valid Shariah reason. Such a refusal makes the wali adhal (unjustly obstructive) and the woman may apply for a judge as wali (wali hakim) (see The marriage wali).

5Religion and character as the foremost measure

Although the schools differ on the other elements, the hadith in at-Tirmidhi 1084 (hasan) and Bukhari 5090 put religion and character first. In practice, this means assessing:

• Prayer, trustworthiness, honesty and how he treats family.
• Record of responsibility — payment of maintenance (nafkah) to an existing wife or children, debts and criminal record.
• Anger management and attitude towards domestic violence.
• Compatibility of creed; the marriage of a Muslim woman to a non-Muslim man is invalid (Surah al-Baqarah 2:221; Surah al-Mumtahanah 60:10) — this is a question of validity, not merely of kafa'ah.

6Kafa'ah in the context of polygyny

For a man who wishes to marry again, the issue of kafa'ah often combines with the issue of means:

• In the Hanafi and Hanbali schools, the ability to pay the mahr and maintenance is an element of kafa'ah. In the Shafi'i school, although wealth is not an element of kafa'ah, justice and maintenance remain obligations that are assessed before taking another wife.
• The woman and her wali have the right to know his marital status, number of dependants and actual income before giving consent.
• In Malaysia, polygyny applications are assessed by the Syariah Court in terms of financial means and justice (Act 303 s.23 and the equivalent provisions in state enactments).

7Current practice

Malaysia: state Islamic family laws do not specifically list the elements of kafa'ah, but it is taken into account through Hukum Syarak (the Shafi'i school) when the court assesses an application for a wali hakim because the wali refuses. The court usually asks: is the man religious and of good character, able to provide maintenance, and are the wali's reasons reasonable?

• The issue of lineage (for example Syed/Sharifah families) still arises in some communities; according to the Shafi'i school, it is a right that can be waived with the consent of the woman and the wali.
• Differences in education and income are now disputed more often than lineage. Contemporary jurists stress that local custom (uruf) can determine what counts as 'an equivalent occupation'.
• Marriage across nations and ethnicities is permissible; what is assessed is religion, character and means, not citizenship.

Other countries: most modern family laws in Arab countries include kafa'ah by giving the wali the right to apply for dissolution if there is no equality; the details vary by country (to be verified for each country).
