What is Allah's Prophet's (saw) opinion about how valuable Haya' (pious shyness from committing religeous indiscretions) is as part of faith?
 Narrated `Abdullah bin `Umar:                     The Prophet passed by a man who was admonishing his brother regarding Haya' (pious shyness from committing religeous indiscretions) 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."
