(5) باب مَا يُكْرَهُ فِي الْمَسَاجِدِ
It was narrated from Wathilah bin Asqa' that:
The Prophet said: "Keep your infants, your insane and your evil ones away from your mosques. Avoid engaging in transactions and disputes, raising your voices, carrying out your prescribed punishments and unsheathing your swords therein. Make places for purification at their gates, and perfume them with incense on Fridays." (Maudu')
