Muttafaq ‘alayh (Bukhari and Muslim) Sahih al-Bukhari 6102
The Prophet (may Allah's peace and blessings be upon him) was more bashful than a virgin in her boudoir. Whenever he saw something he disliked, we could perceive that on his face.
أَشَدَّ حَيَاءً مِنَ الْعَذْرَاءِ فِي خِدْرِهَا، فَإِذَا رَأَى شَيْئًا يَكْرَهُهُ عَرَفْنَاهُ فِي وَجْهِهِ.
