Narrated 'Abdullah bin 'Umar: The Prophet passed by a man who was admonishing his brother regarding Haya and was saying, "You are very shy, and I am afraid that might harm you." On that, Allah's Apostle said, "Leave him, for Haya is (a part) of Faith."
— Sahih Bukhari, Volume 8, Book 73: Good Manners and Form (Al-Adab), Hadith #139
