Arabic (Original)
حَدَّثنا مُحَمَّدُ بْنَ الْمُثَنَّى قَال حَدَّثنا يزيد بن هارون قال أَخْبَرَنَا الْحَجَّاجُ عَنْ قَتَادَةَ عَن الْحَسَنِ عَنْ سَمُرة رَضِي اللَّهُ عَنْهُ قَالَ كَانَ شِعَارُ الْمُهَاجِرِينَ عَبد اللَّهِ وَشِعَارُ الأَنْصَارِ عَبد الرَّحْمَنِ يَعْنِي فِي الْحَرْبِ عَلَى عَهْدِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيه وَسَلَّموَهَذَا الْحَدِيثُ لا نَعْلَمُ رَوَاهُ عَنْ قَتَادَةَ عَن الْحَسَنِ عَنْ سَمُرة إلاَّ الْحَجَّاجُ بْنُ أَرْطَاةَ
English Translation
Narrated Samurah (may Allah be pleased with him): The war cry of the Muhajirun was 'Abdullah' and the war cry of the Ansar was 'Abd al-Rahman' — meaning in battle during the time of the Messenger of Allah (peace and blessings of Allah be upon him). This hadith, we do not know anyone who narrated it from Qatadah from al-Hasan from Samurah except al-Hajjaj ibn Arta'ah.
