'A'isha said, "The Prophet was lying down in my room with his thigh uncovered when Abu Bakr asked for permission to enter. He gave him permission to enter, remaining as he was. Then 'Umar asked for permission to come in and he gave him permission, remaining as he was. Then 'Uthman asked for permission to enter and the Prophet, may Allah bless him and grant him peace, sat up and arranged his garment, and then he came in and spoke. When he left, I said, 'Messenger of Allah, Abu Bakr came in and you did not exert yourself nor concern yourself with him. Then 'Umar came in and you did not exert yourself nor concern yourself with him. Then 'Uthman came in and you sat up and arranged your garment.' He said, 'Should I not be modest before a man before whom the angels are modest?'"
