Sahih al-Bukhari Hadith 4905

We were in a Ghazwa (Sufyan once said, in an army) and a man from the emigrants kicked an Ansari man (on the buttocks with his foot). The Ansari man said, "O the Ansar! (Help!)" and the emigrant said. "O the emigrants! (Help!) Allah's Messenger (ﷺ) heard that and said, "What is this call for, which is characteristic of the period of ignorance?" They said, "O Allah's Messenger (ﷺ)! A man from the emigrants kicked one of the Ansar (on the buttocks with his foot)." Allah's Messenger (ﷺ) said, "Leave it (that call) as is a detestable thing." `Abdullah bin Ubai heard that and said, 'Have the (the emigrants) done so? By Allah, if we return Medina, surely, the more honorable will expel therefrom the meaner." When this statement reached the Prophet. `Umar رضی اللہ عنہ got up an, said, "O Allah's Messenger (ﷺ)! Let me chop off the head of this hypocrite (`Abdullah bin Ubai)!" The Prophet (ﷺ) said "Leave him, lest the people say that Muhammad kills his companions." The Ansar were then more in number than the emigrants when the latter came to Medina, but later on the emigrant increased. Sufyan narrates: I have memorized this Hadith after hearing it from Amr bin Dinnar, and he would say that he heard Hadrat Jabir bin Dinnar رضی اللہ عنہ, and he would say that he heard Hadrat Jabir bin Abdullah رضی اللہ عنہ say: We were accompanying the prophet ﷺ.
