BAYHAQI 17866:
from Jābir b. ʿAbdullāh —
[Machine] And Sufyan said another time, "We were in an army when a man from the Muhajirin struck a man from the Ansar. The Ansari said, 'Oh Ansar!' and the Muhajiri said, 'Oh Muhajireen!' The Messenger of Allah ﷺ heard this and said, 'What is this pre-Islamic cry?' They said, 'A man from the Muhajirin struck a man from the Ansar.' He said, 'Leave it, for it is a call of ignorance.' Abdullah ibn Ubayy heard this in the presence of the Messenger of Allah ﷺ and said, 'They have done it! By Allah, if we return to Al-Madinah, the more honorable will expel the disgraced.' The Messenger of Allah ﷺ heard of this and Umar stood and said, 'O Messenger of Allah, let me strike the neck of this hypocrite.' The Prophet ﷺ said, 'Leave him, for people will say that Muhammad is killing his companions.' The Ansar were more in number than the Muhajirin when they arrived in Al-Madinah, but then the Muhajirin increased in number."
