Full Sharh — Musnad Ahmad 449
حَدَّثَنَا أَبُو الْمُغِيرَةِ، حَدَّثَنَا أَرْطَاةُ يَعْنِي ابْنَ الْمُنْذِرِ، أَخْبَرَنِي أَبُو عَوْنٍ الْأَنْصَارِيُّ، أَنَّ عُثْمَانَ بْنَ عَفَّانَ، رَضِيَ اللَّهُ عَنْهُ قَالَ لِابْنِ مَسْعُودٍ هَلْ أَنْتَ مُنْتَهٍ عَمَّا بَلَغَنِي عَنْكَ فَاعْتَذَرَ بَعْضَ الْعُذْرِ فَقَالَ عُثْمَانُ رَضِيَ اللَّهُ عَنْهُ وَيْحَكَ إِنِّي قَدْ سَمِعْتُ وَحَفِظْتُ وَلَيْسَ كَمَا سَمِعْتَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ سَيُقْتَلُ أَمِيرٌ وَيَنْتَزِي مُنْتَزٍ وَإِنِّي أَنَا الْمَقْتُولُ وَلَيْسَ عُمَرَ رَضِيَ اللَّهُ عَنْهُ إِنَّمَا قَتَلَ عُمَرَ وَاحِدٌ وَإِنَّهُ يُجْتَمَعُ عَلَيَّ.
English Translation
Abu ‘Awn al-Ansari narrated that `Uthman bin `Affan (رضي الله عنه) said to Ibn Mas`ood:: Are you going to give up what I heard about you? He was apologetic, then `Uthman (رضي الله عنه) said: Woe to you! I heard and remembered and it is not as you heard; the Messenger of Allah (ﷺ) said: `A leader will be killed and a criminal will commit a crime.` I am the one who will be killed, not ‘Umar رضي الله عنه); rather ‘Umar (رضي الله عنه) was killed by one man, but a group of people will kill me
