What is the ruling on marrying a young girl? Is the marriage contract with her valid? And if the contract is valid, what is the ruling on enjoying her?

Childhood in Islamic law ends with puberty. Thus, a girl is not described as a minor after reaching puberty, which can occur at an early age. It is not permissible to condemn a girl's early marriage as long as she has reached puberty according to Islamic law and is capable of marriage.

The marriage contract with a minor is valid according to the majority of scholars, with a few dissenting opinions. Some contemporary scholars have chosen to disallow the marriage of a minor unless she gives permission after nine years of age, or if she has reached puberty. The criterion for the validity of marrying a minor is the benefit (maslaha); if this benefit is absent, the contract is nullified.

Regarding the issue of intercourse with or consummating the marriage with a minor: Intercourse with a minor is forbidden if she cannot tolerate it. This is the opinion of the majority of jurists. The time of consummation is tied to her capacity for intercourse, not to a specific age. The principle of "no harm and no causing of harm" must be observed, and the wife should not be handed over before she has reached understanding.
