MADRID -- An imam who wrote a book on how to beat your wife without leaving marks on her body has been ordered by a judge in Spain to study the country's constitution. The judge told Mohamed Kamal Mustafa, imam of a mosque in the southern resort of Fuengirola, to spend six months studying three articles of the constitution and the universal declaration of human rights. Mr. Mustafa was sentenced to 15 months in jail and fined about $2,600 last year after being found guilty of inciting violence against women. A judge released him after 22 days in jail on the condition that he undertake a re-education course. The Spanish government has set up a commission to find ways for the Muslim community to regulate itself. A central recommendation is that imams speak Spanish and have a basic knowledge of human rights and Spanish law. In his book "Women in Islam," published four years ago, Mr. Mustafa wrote that verbal warnings followed by a period of sexual inactivity could be used to discipline a disobedient wife. If that failed, he argued that, according to Islamic law, beatings could be judiciously administered. "The blows should be concentrated on the hands and feet using a rod that is thin and light so that it does not leave scars or bruises on the body," he wrote. Mr. Mustafa's lessons, which he must pay for, will be taught by teachers from Malaga University. According to La Vanguardia newspaper, he will have to study articles 10, 14 and 15 of the constitution. The first two address "the dignity of a person and inviolable rights" and states "all Spaniards are equal before the law." The third one states "the moral and physical integrity of a person in no case can be submitted to torture nor inhuman or degrading punishments or treatment."
