Sahih Bukhari Volume 6, Book 65, Hadith 4907

حَدَّثَنَا عَلِيٌّ، حَدَّثَنَا سُفْيَانُ، قَالَ عَمْرٌو سَمِعْتُ جَابِرَ بْنَ عَبْدِ اللَّهِ ـ رضى الله عنهما ـ قَالَ كُنَّا فِي غَزَاةٍ ـ قَالَ سُفْيَانُ مَرَّةً فِي جَيْشٍ ـ فَكَسَعَ رَجُلٌ مِنَ الْمُهَاجِرِينَ رَجُلاً مِنَ الأَنْصَارِ فَقَالَ الأَنْصَارِيُّ يَا لَلأَنْصَارِ‏.‏ وَقَالَ الْمُهَاجِرِيُّ يَا لَلْمُهَاجِرِينَ‏.‏ فَسَمِعَ ذَاكَ رَسُولُ اللَّهِ صلى الله عليه وسلم فَقَالَ ‏"‏ مَا بَالُ دَعْوَى جَاهِلِيَّةٍ ‏"‏ قَالُوا يَا رَسُولَ اللَّهِ كَسَعَ رَجُلٌ مِنَ الْمُهَاجِرِينَ رَجُلاً مِنَ الأَنْصَارِ‏.‏ فَقَالَ ‏"‏ دَعُوهَا فَإِنَّهَا مُنْتِنَةٌ ‏"‏‏.‏ فَسَمِعَ بِذَلِكَ عَبْدُ اللَّهِ بْنُ أُبَىٍّ فَقَالَ فَعَلُوهَا، أَمَا وَاللَّهِ لَئِنْ رَجَعْنَا إِلَى الْمَدِينَةِ لَيُخْرِجَنَّ الأَعَزُّ مِنْهَا الأَذَلَّ‏.‏ فَبَلَغَ النَّبِيَّ صلى الله عليه وسلم فَقَامَ عُمَرُ فَقَالَ يَا رَسُولَ اللَّهِ دَعْنِي أَضْرِبْ عُنُقَ هَذَا الْمُنَافِقِ‏.‏ فَقَالَ النَّبِيُّ صلى الله عليه وسلم ‏"‏ دَعْهُ لاَ يَتَحَدَّثُ النَّاسُ أَنَّ مُحَمَّدًا يَقْتُلُ أَصْحَابَهُ ‏"‏ وَكَانَتِ الأَنْصَارُ أَكْثَرَ مِنَ الْمُهَاجِرِينَ حِينَ قَدِمُوا الْمَدِينَةَ، ثُمَّ إِنَّ الْمُهَاجِرِينَ كَثُرُوا بَعْدُ‏.‏ قَالَ سُفْيَانُ فَحَفِظْتُهُ مِنْ عَمْرٍو قَالَ عَمْرٌو سَمِعْتُ جَابِرًا كُنَّا مَعَ النَّبِيِّ صلى الله عليه وسلم‏.‏

Narrated By Jabir bin 'Abdullah : 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 Apostle heard that and said, "What is this call for, which is characteristic of the period of ignorance?" They said, "O Allah's Apostle! A man from the emigrants kicked one of the Ansar (on the buttocks with his foot)." Allah's Apostle 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 honourable will expel there-from the meaner." When this statement reached the Prophet. 'Umar got up an, said, "O Allah's Apostle! Let me chop off the head of this hypocrite ('Abdullah bin Ubai)!" The Prophet 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.
