Morocco’s Supreme Scientific Council condemned a fatwa issued by a Salafi preacher that permits girls to marry at the age of nine. The council filed a complaint with the Rabat preliminary court, which has opened an investigation.

The Council said in a statement Sunday that the fatwa issued by Sheikh Mohamed al-Maghrawi has no religious validity since its reasoning is based on only one individual case—the marriage of Prophet Mohamed to Aisha bint Abu-Bakr, who most Muslims believe was nine-years-old, in the 7th century.
