Ayesha reported, "The Messenger of Allah ﷺ was lying down in my house with his thighs, or his shins, uncovered. Abu Bakr asked permission to enter, and he gave him permission while remaining in that state, and they spoke. Then Umar asked permission to enter, and he gave him permission while still in that same state, and they spoke. Then Uthman asked permission to enter, and the Messenger of Allah ﷺ sat up and adjusted his clothing."Muhammad said, "I do not say this happened on a single day."He then entered and they spoke. When Uthman left, Ayesha said, "Abu Bakr came in and you did not stir for him or pay him much mind. Then Umar came in and you did not stir for him or pay him much mind. But when Uthman came in, you sat up and arranged your clothing."He replied, "Should I not feel shy before a man whom even the angels feel shy before?"
كان رسول الله ﷺ مضطجعا في بيتي، كاشفا عن فخذيه، أو ساقيه، فاستأذن أبو بكر، فأذن له، وهو على تلك الحال، فتحدث، ثم استأذن عمر فأذن له، وهو كذلك فتحدث، ثم استأذن عثمان، فجلس رسول الله ﷺ سوى ثيابه- قال محمد: ولا أقول ذلك في يوم أحد- فدخل فتحدث، فلما خرج قالت عائشة: دخل أبو بكر فلم تهتش له، ولم تباله، ثم دخل عمر فلم تهتش له ولم تباله، ثم دخل عثمان فجلست وسويت ثيابك فقال: ألا أستحي من رجل تستحي منه الملائكة.
Muslim narrated it in Fadail al-Sahabah (2401) through several routes from Ismail bin Jafar, from Muhammad bin Abu Harmala, from Ataa and Sulayman, the two sons of Yasar, and from Abu Salama bin Abdul-Rahman, that Ayesha said, and then he related the account.Tahawi narrated it in Sharh Mushkil Athar (1695) through another route from Muhammad bin Abu Harmala with his chain, without the uncertainty, stating plainly that what was uncovered was the thigh.A similar version was narrated from Hafsa bint Umar bin Khattab, who said, "One day the Messenger of Allah ﷺ had placed a garment between his thighs," and then she related the story. Ahmad narrated it (26466), Tabarani in Al-Kabir (23/217–218), and Bayhaqi in his Sunan (2/231), all of them from the hadith of Ibn Jurayj, who said, Abu Khalid informed me, from Abdullah bin Abu Saeed Madani, who said, Hafsa bint Umar bin Khattab narrated to me, and he related something similar.Abdullah bin Abu Saeed Madani is majhul, and he is among the men listed in Tajil. The correct view is that the incident took place in Ayesha's house, so it is unlikely that Hafsa was also present in the house, or that she heard it from Ayesha, in which case the hadith would trace back to Ayesha's musnad.
