To avoid causing offence, the following information guidelines in Brunei Darussalam should be observed:

• Leave footwear in the assigned place outside the mosque before entering.
  
• Both men and women are not allowed to enter with bare legs or shoulders (some mosques may be able to  lend a robe).
  
• Women should cover their head.
  
• Do not walk in front of a praying person.
  
• Non-Muslims are not allowed to touch the Quran.
