Sufyan narrated from Amr bin Dinar that he heard Jabir bin Abdullah saying: “We were in a battle” – Sufyan said: “They say it was the battle of Banu Mustaliq” – “A man from the Muhajirin kicked a man from the Ansar. The man from the Muhajirin said: ‘O Muhajirin!’ the man from the Ansar said: ‘O Ansar!’ The Prophet (ﷺ) heard that and said: ‘What is this evil call of Jahliyyah?’ They said: ‘A man from the Muhajirin kicked a man from the Ansar.’ So the Prophet (ﷺ) said: ‘Leave that, for it is offensive.’ Abdullah bin Ubayy bin Salul heard that and said: ‘Did they really do that? By Allah! If we return to Al-Madinah indeed the more honorable will expel therefrom the meaner.’ Umar said: ‘Allow me to chop off the head of this hypocrite, O Messenger of Allah!’ The Prophet (ﷺ) said: ‘Leave him, I do not want the people to say that Muhammad kills his Companions.’” Someone other than Amr said: “So his son, Abdullah bin Abdullah, said: ‘By Allah! You shall not return until you say that you are the mean and that the Messenger of Allah (ﷺ) is the honorable.’ So he did so.”
