Full Sharh — Musnad Ahmad 414
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ بَكْرٍ، حَدَّثَنَا حُمَيْدٌ الطَّوِيلُ، عَنْ شَيْخٍ، مِنْ ثَقِيفٍ ذَكَرَهُ حُمَيْدٌ بِصَلَاحٍ ذَكَرَ أَنَّ عَمَّهُ أخْبَرَهُ أَنَّهُ رَأَى عُثْمَانَ بْنَ عَفَّانَ رَضِيَ اللَّهُ عَنْهُ جَلَسَ عَلَى الْبَابِ الثَّانِي مِنْ مَسْجِدِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَدَعَا بِكَتِفٍ فَتَعَرَّقَهَا ثُمَّ قَامَ فَصَلَّى وَلَمْ يَتَوَضَّأْ ثُمَّ قَالَ جَلَسْتُ مَجْلِسَ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَأَكَلْتُ مَا أَكَلَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَصَنَعْتُ مَا صَنَعَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ.
English Translation
It was narrated that an old man of Thaqeef - Humaid said that he was righteous - said that his paternal uncle told him that he saw `Uthman (رضي الله عنه) sitting at the second door of the mosque of the Messenger of Allah (ﷺ) . He called for a shoulder and ate its meat, then he got up and prayed, without doing wudoo’. Then he said:: I sat where the Prophet (ﷺ) sat and I ate what the Prophet (ﷺ) ate, and I did what the Prophet (ﷺ) did.
