The Lucerne justice authorities had opened an inquiry against the man following reports that the imam advised followers to discipline their wives with physical violence if they disobey.
The incident allegedly occurred during a speech at a Friday prayer session in August.
The imam was briefly detained by police for questioning pending a legal investigation. The umbrella group recommended that the speeches at a mosque be recorded and kept for at least 12 months.
It is the latest case involving controversial imams at mosques in Switzerland.
Earlier this week, the highest court confirmed a decision not to renew the residence permit of an imam working in eastern Switzerland guilty of domestic abuse.
