AbdurRahman ibn Mu'adh said that he heard a man from the Companions of the Prophet (ﷺ) say:
The Prophet (ﷺ) addressed the people at Mina and he made them stay in their dwellings. He then said: The Muhajirun (Emigrants) should stay here, and he made a sign to the right side of the qiblah, and the Ansar (the Helpers) here, and he made a sign to the left side of the qiblah; the people should stay around them.
حَدَّثَنَا أَحْمَدُ بْنُ حَنْبَلٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، أَخْبَرَنَا مَعْمَرٌ، عَنْ حُمَيْدٍ الأَعْرَجِ، عَنْ مُحَمَّدِ بْنِ إِبْرَاهِيمَ التَّيْمِيِّ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ مُعَاذٍ، عَنْ رَجُلٍ، مِنْ أَصْحَابِ النَّبِيِّ صلى الله عليه وسلم قَالَ خَطَبَ النَّبِيُّ صلى الله عليه وسلم النَّاسَ بِمِنًى وَنَزَّلَهُمْ مَنَازِلَهُمْ فَقَالَ " لِيَنْزِلِ الْمُهَاجِرُونَ هَا هُنَا " . وَأَشَارَ إِلَى مَيْمَنَةِ الْقِبْلَةِ " وَالأَنْصَارُ هَا هُنَا " . وَأَشَارَ إِلَى مَيْسَرَةِ الْقِبْلَةِ " ثُمَّ لْيَنْزِلِ النَّاسُ حَوْلَهُمْ " .
