Here, modesty is seen no less important in speech and behavior than in dressing. Again, modesty has a dual aspect in Islam: modesty is to be maintained in public which is generally related to people, as well as in private which is related to God.[52] Islam expects that a Muslim who believes in God will feel shy in front of God, and this shyness will prevent him from disobeying God, from committing any sinful or immodest act, whether in public or private, because he has awareness of God.[52] Muhammad has said, "Modesty is part of faith" (Sahih al-Bukhari, 8:73:139).
