The Messenger of Allah (may Allah’s peace and blessings be upon him) was more bashful than a virgin in her boudoir. Whenever he saw anything he disliked, we could perceive it on his face. [Al-Bukhari ]

"عن أبي سعيد الخدري -رضي الله عنه- قال: كان رسول الله -صلى الله عليه وسلم- أَشَدَّ حياءً من العَذْرَاءِ في خِدْرِهَا، فإذا رأى شيئا يَكْرَهُهُ عرفناه في وجهه. [صحيح.] - [متفق عليه.]"
