The marriage of minors in the four Sunni legal schools

Introduction

In the classical Muslim legal tradition, the issue of child marriage is subject to a principle of agreement among the four major Sunni schools of jurisprudence. All, in theory, recognize the validity of marrying a girl who has not yet reached puberty, based on the Quran and prophetic tradition, while framing this possibility with stringent conditions related to the child's best interests (general interest — maslaha) and the absence of harm.

Behind this apparent consensus, important nuances appear regarding the role of the guardian and the guarantees provided to the minor.

Authorization framed by the guardian's role

The Hanafi school permits the marriage of a minor under the authority of the father or grandfather, considered legitimate guardians. However, it provides a protection mechanism: if the marriage was arranged by another guardian, the young girl can, upon reaching puberty, exercise a "choice at puberty" (khiyar al-bulugh), meaning confirm or annul the union. As summarized by a classic work:

"As for the tutorship of recommendation and coercion, it is established for the father and grandfather concerning the male and female minors…" (Badā’i‘ al-Sanā’i‘, Imam Al-Kasani, vol. 2, p. 241)

On the Maliki side, the position is more restrictive regarding the designation of the guardian. Only the father is authorized to contract this marriage, as a compelling guardian (wali mujbir), with the possibility to do so without the minor’s explicit consent:

"The father has the right to marry his minor virgin daughter without her consent…" (Minah al-Jalīl, Sheikh Muhammad ‘Alish, vol. 3, p. 348)

Shafi'i jurists also acknowledge this prerogative to the father and grandfather. But they introduce an ethical reservation, recommending to wait for the girl’s puberty to seek her opinion:

"It is permissible for the father and grandfather to marry the minor virgin… but it is preferable not to marry her before she is pubescent." (Rawdat al-Tālibīn, Imam Al-Nawawi, vol. 7, p. 51)

The Hanbali school follows this continuity, mainly recognizing this right to the father—and, according to some opinions, to the grandfather—based on prophetic tradition:

"As for the minor virgin, there is no divergence regarding the fact that the father may marry her… according to the hadith of Aisha." (Al-Mughnī, Imam Ibn Qudama, vol. 9, p. 398)

The minor’s best interest as a central principle

Despite these differences, a cross-cutting principle prevails: that of the minor's interest (maslaha). Jurists emphasize that the marriage must be beneficial to her. In case of harm—physical or psychological—the union becomes illicit, in accordance with a fundamental legal principle: the prohibition of harm to others.

Another essential distinction is that between the conclusion of the marriage and its consummation. While the contract can be established under certain conditions before puberty, marital relations are strictly conditioned by the young girl's physical capacity. Traditionally assessed according to custom (‘urf), and, in contemporary approaches, in light of medical criteria.

Between legal heritage and contemporary challenges

These positions, stemming from classical law, continue to fuel contemporary debates. In many Muslim-majority countries, legislation has established a legal minimum age for marriage, marking a significant evolution.

Nonetheless, these doctrines reflect an ancient legal framework where the child’s interest, consent, and protection remain central—concepts that are today reinterpreted in light of modern standards.
