[Machine] The Prophet Muhammad ﷺ was lying down in his home, with his thighs or legs exposed. Abu Bakr sought permission to enter, and he was granted permission while the Prophet remained in that position. They spoke, then Umar sought permission and he was granted permission while the Prophet remained in the same position. They spoke again, then Uthman sought permission and the Prophet sat up and fixed his clothing. Muhammad said, "I do not speak of this in a single day." After Uthman left, Aisha said, "O Messenger of Allah, Abu Bakr entered and you did not pay attention to him nor did you mind it. Then Umar entered and you did not pay attention to him nor did you mind it. Then Uthman entered and you sat up and fixed your clothing. Shouldn't you feel shy before a man that the angels feel shy before?" I am paraphrasing the narration of Qutaybah.
كَانَ رَسُولُ اللهِ ﷺ مُضْطَجِعًا فِي بَيْتِهِ كَاشِفًا عَنْ فَخِذَيْهِ أَوْ سَاقَيْهِ فَاسْتَأْذَنَ أَبُو بَكْرٍ فَأَذِنَ لَهُ وَهُوَ عَلَى تِلْكَ الْحَالِ فَتَحَدَّثَ ثُمَّ اسْتَأْذَنَ عُمَرُ فَأَذِنَ لِعُمَرَ وَهُوَ كَذَلِكَ فَتَحَدَّثَ ثُمَّ اسْتَأْذَنَ عُثْمَانُ فَجَلَسَ رَسُولُ اللهِ ﷺ وَسَوَّى ثِيَابَهُ قَالَ مُحَمَّدٌ وَلَا أَقُولُ ذَلِكَ فِي يَوْمٍ وَاحِدٍ فَتَحَدَّثَ فَلَمَّا خَرَجَ قَالَتْ عَائِشَةُ يَا رَسُولَ اللهِ دَخَلَ أَبُو بَكْرٍ فَلَمْ تَهْتَشَّ لَهُ وَلَمْ تُبَالِهِ ثُمَّ دَخَلَ عُمَرُ فَلَمْ تَهْتَشَّ لَهُ وَلَمْ تُبَالِهِ ثُمَّ دَخَلَ عُثْمَانُ فَجَلَسْتَ وَسَوَّيْتَ ثِيَابَكَ فَقَالَ أَلَا أَسْتَحْيِي مِنْ رَجُلٍ تَسْتَحْيِي مِنْهُ الْمَلَائِكَةُ لَفْظُ حَدِيثِ قُتَيْبَةَ
