[6583] 63 - (...) Sufyân bin 'Uyaynah said: "Amr heard Jâbir bin 'Abdullâh say: 'We were with the Messenger of Allâh ﷺ on a campaign, when a man of the Muhâjirîn hit a man of the Anshâr from behind. The Anshâr said: 'O Anshâr!' And the Muhâjir said: 'O Muhâjirîn!' The Messenger of Allâh ﷺ said: 'What is this call of Jâhilîyyah?' They said: 'O Messenger of Allâh, a man of the Muhâjirîn hit a man of the Anshâr from behind.' He said: 'Stay away from it, it is disgusting.'" "Abdullâh bin Ubayy heard it and said: 'They have done it, by Allâh. If we return to Al-Madînah, indeed the more honorable (referring to himself) will expel therefrom the meaner.'[1] 'Umar said: 'Let me strike the neck of this hypocrite.' He (ﷺ) said: 'Let him be, lest the people say that Muḥammad kills his Companions.'"
