(LoL) Etiquette of entering the Musjid for a non-Muslim:
• Enter the Musjid with your right foot. When leaving,come out with your left foot.
• If somebody is praying, you should not pass in front of him.
• The mosque must always be kept clean and if possible some scent/Atr should be used here; nothing dirty should be left here.
• You should not eat anything that gives bad smell, before going to the mosque; your mouth odour will be very disturbing to others.
• You should not spit inside the mosque or on its stairs.
• Those who come late should not jump over the heads of others to go to the front lines.
• Small children who might make noise or who might urinate here, should not be brought to the Mosque.
