Pro-Uthman

حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، وَيَحْيَى بْنُ أَيُّوبَ، وَقُتَيْبَةُ، وَابْنُ، حُجْرٍ قَالَ يَحْيَى بْنُ يَحْيَى أَخْبَرَنَا وَقَالَ الآخَرُونَ، حَدَّثَنَا إِسْمَاعِيلُ، - يَعْنُونَ ابْنَ جَعْفَرٍ - عَنْ مُحَمَّدِ بْنِ أَبِي حَرْمَلَةَ، عَنْ عَطَاءٍ، وَسُلَيْمَانَ، ابْنَىْ يَسَارٍ وَأَبِي سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ أَنَّ عَائِشَةَ، قَالَتْ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم مُضْطَجِعًا فِي بَيْتِي كَاشِفًا عَنْ فَخِذَيْهِ أَوْ سَاقَيْهِ فَاسْتَأْذَنَ أَبُو بَكْرٍ فَأَذِنَ لَهُ وَهُوَ عَلَى تِلْكَ الْحَالِ فَتَحَدَّثَ ثُمَّ اسْتَأْذَنَ عُمَرُ فَأَذِنَ لَهُ وَهُوَ كَذَلِكَ فَتَحَدَّثَ ثُمَّ اسْتَأْذَنَ عُثْمَانُ فَجَلَسَ رَسُولُ اللَّهِ صلى الله عليه وسلم وَسَوَّى ثِيَابَهُ - قَالَ مُحَمَّدٌ وَلاَ أَقُولُ ذَلِكَ فِي يَوْمٍ وَاحِدٍ - فَدَخَلَ فَتَحَدَّثَ فَلَمَّا خَرَجَ قَالَتْ عَائِشَةُ دَخَلَ أَبُو بَكْرٍ فَلَمْ تَهْتَشَّ لَهُ وَلَمْ تُبَالِهِ ثُمَّ دَخَلَ عُمَرُ فَلَمْ تَهْتَشَّ لَهُ وَلَمْ تُبَالِهِ ثُمَّ دَخَلَ عُثْمَانُ فَجَلَسْتَ وَسَوَّيْتَ ثِيَابَكَ فَقَالَ ‏ "‏ أَلاَ أَسْتَحِي مِنْ رَجُلٍ تَسْتَحِي مِنْهُ الْمَلاَئِكَةُ ‏"‏ ‏.‏

Aisha reported: Allah's Messenger (ﷺ) was lying in the bed in my apartment with his thigh uncovered and Abu Bakr sought permission to enter. It was given to him and he conversed in the same very state (the Prophet's thigh or shank uncovered). Then Umar sought permission for entering and it was given to him and he conversed in that very state. Then Uthman sought permission to enter; Allah's Messenger (ﷺ) sat down and he set right his clothes. Muhammad (one of the narrators) said: I do not say that it happened on the same day. He (Uthman) then entered and conversed and as he went out, Aisha said: Abu Bakr entered and you did not stir and did not observe much care (in arranging your clothes), then Umar entered and you did not stir and did not arrange your clothes, then `Uthman entered and you got up and set your clothes right, so he (ﷺ) said: Should I not show modesty to one whom even the Angels show modesty.
