Nur Fazira Saad and Fahmi Alias married last week in northern Kedah state after the girl’s father agreed to the union and an Islamic court granted permission, The Star daily reported.
“It is better for them to get married rather than doing something improper,” Saad Mustafa, the girl’s father, was quoted as saying.
But Ratna Osman, executive director of activist group Sisters in Islam, described the young couple’s marriage as “shocking”.
“I don’t understand why this is allowed in a country like Malaysia… We are talking about a developed country,” she told AFP. “The concern is that this is a child being married off… No parents should be doing this.”
Child marriages are not uncommon in the conservative Southeast Asian country, where 60 percent of the population of 29 million people are Muslim.
Two years ago, the marriage of a 14-year-old Muslim girl to a 23-year-old schoolteacher triggered similar calls for reform.
Girls below the age of 16 must obtain the permission of Islamic courts, which regulate civil matters for Muslims. But activists say such permission is too readily granted.
There was another outcry in October when two men, aged 19 and 22, were released on probation after courts convicted them of statutory rape.
In both cases the girls, aged 12 and 13, had not been forced, lawyers said.
But activists slammed the judges for freeing the men, saying the question of consent should not have arisen as the victims were below 16.
Earlier this week, a high court overturned the ruling in one of the cases, jailing the 22-year-old man for five and a half years.
