Abu Barza reported,

We were with Abu Bakr al-Siddiq رضي الله عنه while he was carrying out his duties when he became angry with a man from among the Muslims. His anger against him grew very intense. When I saw this, I said, "Caliph of the Messenger of Allah, shall I strike off his neck?"When I mentioned killing, he turned away entirely from that subject to other matters. After we had dispersed, Abu Bakr al-Siddiq رضي الله عنه sent for me later and said, "Abu Barzah, what did you say?"I had forgotten what I had said, so I replied, "Remind me of it. I do not remember what I said."He said, "Do you not remember what you said?"I said, "No, by Allah."He said, "Do you not recall when you saw me angry with the man and you said, 'Shall I strike off his neck, Caliph of the Messenger of Allah?' Do you not remember that? Would you really have done it?"I said, "Yes, by Allah, and even now, if you command me, I will do it."He said, "Woe to you! By Allah, that authority belongs to no one after Muhammad ﷺ."

Sahih

حدثنا عفان حدثنا يزيد بن زريع حدثنا يونس بن عبيد عن حميد بن هلال عن عبد الله بن مطرف بن الشخير أنه حدثهم

عن أبي برزة الأسلمي أنه قال

كنا عند أبي بكر الصديق رضي الله عنه في عمله فغضب على رجل من المسلمين فاشتد غضبه عليه جدا فلما رأيت ذلك قلت يا خليفة رسول الله أضرب عنقه فلما ذكرت القتل صرف عن ذلك الحديث أجمع إلى غير ذلك من النحو فلما تفرقنا أرسل إلي بعد ذلك أبو بكر الصديق رضي الله عنه فقال يا أبا برزة ما قلت قال ونسيت الذي قلت قلت ذكرنيه قال أما تذكر ما قلت قال قلت لا والله قال أرأيت حين رأيتني غضبت على الرجل فقلت أضرب عنقه يا خليفة رسول الله أما تذكر ذاك أوكنت فاعلا ذاك قال قلت نعم والله والآن إن أمرتني فعلت قال ويحك أو ويلك إن تلك والله ما هي لأحد بعد محمد ﷺ
