According to local tales circulating in urban areas like Casablanca and Rabat, there exists an unusual noise regulation that allegedly mandates neighbours to limit their voice volume, especially after sunset, to prevent disturbances and uphold public order. While there is no official record widely confirming this exact rule, it is often described as a traditional custom evolving into an informal social norm respected by many households. The legend says that raising one’s voice beyond a whisper could result in fines or visits by local officials, though such enforcement appears anecdotal. This so-called "Whisper Rule" is frequently mentioned to explain the peaceful/block-wide quietness experienced in certain Moroccan neighborhoods during the evening. It reflects a cultural emphasis on communal harmony and respect for neighbours, tying into broader public order and noise control practices known throughout Moroccan society. Regardless of its legal authenticity, the story endures as a curious example of how local customs sometimes blur the line between law and social etiquette. Given the scarcity of official documentation, this entry remains in the realm of local-lore rather than confirmed legislation.
