Musnad Ahmad, 537
da’if· Darussalam

It was narrated that al-Hasan bin Abil-Hasan said:

l entered the mosque and I saw `Uthman bin `Affan (رضي الله عنه) reclining on his rida`. Two water carriers came to him and he judged between them. Then I came to him and looked at him; he was a handsome man with marks of smallpox on his face and his arms were covered with hair.

حَدَّثَنَا عَبْد اللَّهِ، حَدَّثَنِي زِيَادُ بْنُ أَيُّوبَ، حَدَّثَنَا هُشَيْمٌ، قَالَ زَعَمَ أَبُو الْمِقْدَامِ عَنِ الْحَسَنِ بْنِ أَبِي الْحَسَنِ، قَالَ دَخَلْتُ الْمَسْجِدَ فَإِذَا أَنَا بِعُثْمَانَ بْنِ عَفَّانَ، رَضِيَ اللَّهُ عَنْهُ مُتَّكِئٌ عَلَى رِدَائِهِ فَأَتَاهُ سَقَّاءَانِ يَخْتَصِمَانِ إِلَيْهِ فَقَضَى بَيْنَهُمَا ثُمَّ أَتَيْتُهُ فَنَظَرْتُ إِلَيْهِ فَإِذَا رَجُلٌ حَسَنُ الْوَجْهِ بِوَجْنَتِهِ نَكَتَاتُ جُدَرِيٍّ وَإِذَا شَعْرُهُ قَدْ كَسَا ذِرَاعَيْهِ‏.‏
