We were with Abu Bakr as-Siddeeq when he was conducting some business of caliphate and he got very angry with one of the Muslims. When I saw that I said: O Khaleefah of the Messenger of Allah, shall I strike his neck? When I mentioned killing him, he changed the subject completely, When we parted, Abu Bakr as Siddeeq sent word to me after that and said: O Abu Barzah, what did you say? I said: I have forgotten what I said; remind me. He said: Don't you remember what you said? I said: No, by Allah. He said: Do you remember, when you saw me get angry with that man, you said: Shall I strike his neck, O khaleefah of the Messenger of Allah? Don't you remember that? would you really have done that? I said: Yes, by Allah. If you order me to do it now, I will do it. He said: Woe to you! By Allah, that is not for anyone after Muhammad ﷺ.  

أَنَّهُ قَالَ كُنَّا عِنْدَ أَبِي بَكْرٍ الصِّدِّيقِ فِي عَمَلِهِ فَغَضِبَ عَلَى رَجُلٍ مِنَ الْمُسْلِمِينَ فَاشْتَدَّ غَضَبُهُ عَلَيْهِ جِدًّا فَلَمَّا رَأَيْتُ ذَلِكَ قُلْتُ يَا خَلِيفَةَ رَسُولِ اللهِ أَضْرِبُ عُنُقَهُ فَلَمَّا ذَكَرْتُ الْقَتْلَ صَرَفَ عَنْ ذَلِكَ الْحَدِيثِ أَجْمَعَ إِلَى غَيْرِ ذَلِكَ مِنَ النَّحْوِ فَلَمَّا تَفَرَّقْنَا أَرْسَلَ إِلَيَّ بَعْدَ ذَلِكَ أَبُو بَكْرٍ الصِّدِّيقُ فَقَالَ يَا أَبَا بَرْزَةَ مَا قُلْتَ؟ قَالَ وَنَسِيتُ الَّذِي قُلْتُ قُلْتُ ذَكِّرْنِيهِ قَالَ أَمَا تَذْكُرُ مَا قُلْتَ؟ قَالَ قُلْتُ لَا وَاللهِ قَالَ أَرَأَيْتَ حِينَ رَأَيْتَنِي غَضِبْتُ عَلَى الرَّجُلِ فَقُلْتَ أَضْرِبُ عُنُقَهُ يَا خَلِيفَةَ رَسُولِ اللهِ؟ أَمَا تَذْكُرُ ذَاكَ؟ أَوَ كُنْتَ فَاعِلًا ذَاكَ؟ قَالَ قُلْتُ نَعَمْ وَاللهِ وَالْآنَ إِنْ أَمَرْتَنِي فَعَلْتُ قَالَ وَيْحَكَ أَوْ وَيْلَكَ إِنَّ تِلْكَوَاللهِ مَا هِيَ لِأَحَدٍ بَعْدَ مُحَمَّدٍ ﷺ  

"We were with Abu Bakr As-Siddiq, and he got angry with a man from among the Muslims, and became very angry indeed. When I saw that, I said: 'O Khalifah of the Messenger of Allah, shall I strike his neck?' When I mentioned killing him, he stopped being angry with him and changed the subject. When we parted, he sent for me and said: 'O Abu Barzah, what did you say?' I said: 'I have forgotten what I said; remind me.' He said: 'Do you not remember what you said?' I said: 'No, by Allah.' He said: 'Don't you remember, when you saw me angry with a man, and said, 'I will strike his neck O Khalifah of the Messenger of Allah?' Don't you remember that? Would you really have done that?' I said: 'Yes, by Allah, and if you tell me to do it now, I will do it.' He said: 'By Allah, that is not for anyone after Muhammad [SAW].'" (Using translation from Nasāʾī 4077)
