Abu Sa'eed Khudari (may Allah be pleased with him) says that Messenger of Allah ﷺ was more bashful than a virgin girl in her veil (purdah). When Messenger of Allah ﷺ did not like something, it could be seen on his face. (Because of his excessive Modesty he did not mention it).

حَدَّثَنَا مَحْمُودُ بْنُ غَيْلانَ، قَالَ: حَدَّثَنَا أَبُو دَاوُدَ، قَالَ: حَدَّثَنَا شُعْبَةُ، عَنْ قَتَادَةَ، قَالَ: سَمِعْتُ عَبْدَ اللهِ بْنَ أَبِي عُتْبَةَ، يُحَدِّثُ عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، قَالَ: كَانَ النَّبِيُّ ﷺ أَشدَّ حَيَاءً مِنَ الْعَذرَاءِ فِي خِدْرِهَا، وَكَانَ إِذَا كَرِهَ شَيْئًا عَرَفْنَاهُ فِي وَجْهِهِ.
