Sayyiduna Anas (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) was more modest than a secluded maiden behind her curtain. When something displeased him, we would know it from his (peace and blessings be upon him) face. The Prophet (peace and blessings be upon him) said: "Modesty is good, all of it."
Imam al-Bazzar recorded this narration, and the narrators of this narration are the narrators of the Sahih, except for Muhammad bin Umar al-Muqaddami, whose case is different, and he is thiqah (trustworthy).
