Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates: The Prophet Muhammad (peace be upon him) passed by a man who was advising his brother regarding modesty. The Prophet Muhammad (peace be upon him) said: Leave him, for modesty is a part of faith.
(Imam Ibn Hibban, may Allah have mercy on him, says:): The words of the narration: "Leave him." This refers to a prohibition that is applied anew at the beginning of the matter.
