It is narrated from Sayyiduna Abu Barzah Aslami (may Allah be pleased with him) that once we were engaged in some work with Sayyiduna Abu Bakr Siddiq (may Allah be pleased with him). During this, Sayyiduna Abu Bakr Siddiq (may Allah be pleased with him) became angry with a Muslim for some reason, and his anger increased greatly. When I saw the situation, I said, "O Successor of the Messenger of Allah! Should I not strike his neck?" When I mentioned killing, he changed the subject and topic of conversation altogether. When we dispersed after finishing there, Sayyiduna Abu Bakr Siddiq (may Allah be pleased with him) sent for me through a messenger and said, "Abu Barzah! What were you saying?" I replied, "By Allah, I do not remember." He said, "Recall, when you saw me angry with a person, you said, 'O Successor of the Messenger of Allah! Should I not strike his neck?' Do you remember? Would you really have done so?" I swore and replied, "Yes! If you even now command me, I will carry it out." He said, "Alas! By Allah! After the Prophet (peace and blessings be upon him), this is not for anyone."
