[1]. It is narrated on the authority of Abu Huraira that the Messenger of Allah (PBUH) said:
Faith has over seventy branches, the most excellent of which is the declaration that there is no god but Allah, and the humblest of which is the removal of what is injurious from the path: and modesty is the branch of faith.(Abu Daud 4058)
[2]. Once Allah’s Messenger (PBUH) passed by an Ansari (man) who was admonishing his brother regarding Haya’. On that Allah’s Messenger (PBUH) said, “Leave him as Haya’ is a part of faith.” (Bukhari, 23)
[3]. It was narrated from Abu Bakrah that the Messenger of Allah (PBUH) said:
“Modesty is part of faith, and faith will be in Paradise. Obscenity in speech is part of harshness and harshness will be in Hell.” (Musnad Ahmad 10292)
