Sahih Bukhari Volume 6, Book 65, Hadith 4909

حَدَّثَنَا الْحُمَيْدِيُّ، حَدَّثَنَا سُفْيَانُ، قَالَ حَفِظْنَاهُ مِنْ عَمْرِو بْنِ دِينَارٍ قَالَ سَمِعْتُ جَابِرَ بْنَ عَبْدِ اللَّهِ ـ رضى الله عنهما ـ يَقُولُ كُنَّا فِي غَزَاةٍ فَكَسَعَ رَجُلٌ مِنَ الْمُهَاجِرِينَ رَجُلاً مِنَ الأَنْصَارِ فَقَالَ الأَنْصَارِيُّ يَا لَلأَنْصَارِ‏.‏ وَقَالَ الْمُهَاجِرِيُّ يَا لَلْمُهَاجِرِينَ‏.‏ فَسَمَّعَهَا اللَّهُ رَسُولَهُ صلى الله عليه وسلم قَالَ ‏"‏ مَا هَذَا ‏"‏‏.‏ فَقَالُوا كَسَعَ رَجُلٌ مِنَ الْمُهَاجِرِينَ رَجُلاً مِنَ الأَنْصَارِ فَقَالَ الأَنْصَارِيُّ يَا لَلأَنْصَارِ‏.‏ وَقَالَ الْمُهَاجِرِيُّ يَالَلْمُهَاجِرِينَ‏.‏ فَقَالَ النَّبِيُّ صلى الله عليه وسلم ‏"‏ دَعُوهَا فَإِنَّهَا مُنْتِنَةٌ ‏"‏‏.‏ قَالَ جَابِرٌ وَكَانَتِ الأَنْصَارُ حِينَ قَدِمَ النَّبِيُّ صلى الله عليه وسلم أَكْثَرَ، ثُمَّ كَثُرَ الْمُهَاجِرُونَ بَعْدُ، فَقَالَ عَبْدُ اللَّهِ بْنُ أُبَىٍّ أَوَقَدْ فَعَلُوا، وَاللَّهِ لَئِنْ رَجَعْنَا إِلَى الْمَدِينَةِ لَيُخْرِجَنَّ الأَعَزُّ مِنْهَا الأَذَلَّ‏.‏ فَقَالَ عُمَرُ بْنُ الْخَطَّابِ رضى الله عنه دَعْنِي يَا رَسُولَ اللَّهِ أَضْرِبْ عُنُقَ هَذَا الْمُنَافِقِ‏.‏ قَالَ النَّبِيُّ صلى الله عليه وسلم ‏"‏ دَعْهُ لاَ يَتَحَدَّثُ النَّاسُ أَنَّ مُحَمَّدًا يَقْتُلُ أَصْحَابَهُ ‏"‏‏.‏

Narrated By Jabir bin Abdullah : We were in a Ghazwa and a man from the emigrants kicked an Ansari (on the buttocks with his foot). The Ansari man said, "O the Ansari! (Help!)" The emigrant said, "O the emigrants! (Help)." When Allah's Apostle heard that, he said, "What is that?" They said, "A man from the emigrants kicked a man from the Ansar (on the buttocks his foot). On that the Ansar said, 'O the Ansar!' and the emigrant said, 'O the emigrants!" The Prophet said' "Leave it (that call) for it Is a detestable thing." The number of Ansar was larger (than that of the emigrants) at the time when the Prophet came to Medina, but later the number of emigrants increased. 'Abdullah bin Ubai said, "Have they, (the emigrants) done so? By Allah, if we return to Medina, surely, the more honourable will expel there-from the meaner," 'Umar bin Al-Khattab said, "O Allah's Apostle! Let me chop off the head of this hypocrite!" The Prophet said, "Leave him, lest the people say Muhammad kills his companions."
