Uthman and Aisha reported,

Abu Bakr رضي الله عنه asked permission to come in to the Messenger of Allah ﷺ while he was lying on his bed wearing Ayesha's رضي الله عنها cloak. He gave Abu Bakr permission while he was in that state, and Abu Bakr settled his business with him and then left. Then Umar asked permission, and he gave him permission while he was in that same state, and Umar settled his business with him and then left.Uthman said, "Then I asked permission to come in to him, and he sat up and said to Ayesha, 'Gather your clothes about you.' Then he settled my business with me, and I left."Ayesha said, "Messenger of Allah, why did I not see you show concern for Abu Bakr and Umar as you showed concern for Uthman?"The Messenger of Allah ﷺ answered, "Uthman is a modest man, and I feared that if I gave him permission in that state, he would not be able to tell me what he needed."Layth said that a group of people reported that the Messenger of Allah ﷺ said to Ayesha, "Should I not feel shy before a man before whom the angels feel shy?"
