In Marseille, on the southern coast, “conversions have increased at an incredible pace in the last three years,” said Abderrahmane Ghoul, the imam of the major mosque of Marseille and the president of the local branch of the French Council of the Muslim Faith. Mr. Ghoul signed about 130 conversion certificates in 2012.
Hassen Chalghoumi, the moderate imam of Drancy, another suburb near Paris, says he thinks conversions have also been propelled by France’s official secularism, which he says breeds spiritual emptiness.
“Secularism has become antireligious,” Mr. Chalghoumi said. “Therefore, it has created an opposite phenomenon. It has allowed people to discover Islam.”
