If he was in a room with the door closed, and he took off his garment to pour water on himself, shyness prevented him from standing up straight.  

أحمد:٥٤٣ – حَدَّثَنَا عَبْدُ الصَّمَدِ حَدَّثَنَا سَالِمٌ أَبُو جُمَيْعٍحَدَّثَنَا الْحَسَنُ وَذَكَرَ عُثْمَانَ وَشِدَّةَ حَيَائِهِ فَقَالَ

إِنْ كَانَ لَيَكُونُ فِي الْبَيْتِ وَالْبَابُ عَلَيْهِ مُغْلَقٌ فَمَا يَضَعُ عَنْهُ الثَّوْبَ لِيُفِيضَ عَلَيْهِ الْمَاءَ يَمْنَعُهُ الْحَيَاءُ أَنْ يُقِيمَ صُلْبَهُ
