ʿUmar said, "When the Prophet ﷺ died I said to Abu Bakr, 'Let us go to our Ansari brethren.' We met two pious men from them, who had fought in the battle of Badr." When I mentioned this to ʿUrwa bin Az-Zubair, he said, "Those two pious men were 'Uwaim bin Saʿida and Manbin Adi."  

البخاري:٤٠٢١حَدَّثَنَا مُوسَى حَدَّثَنَا عَبْدُ الْوَاحِدِ حَدَّثَنَا مَعْمَرٌ عَنِ الزُّهْرِيِّ عَنْ عُبَيْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ حَدَّثَنِي ابْنُ عَبَّاسٍ

عَنْ عُمَرَ ؓ لَمَّا تُوُفِّيَ النَّبِيُّ ﷺ قُلْتُ لأَبِي بَكْرٍ انْطَلِقْ بِنَا إِلَى إِخْوَانِنَا مِنَ الأَنْصَارِ فَلَقِيَنَا مِنْهُمْ رَجُلاَنِ صَالِحَانِ شَهِدَا بَدْرًا فَحَدَّثْتُ عُرْوَةَ بْنَ الزُّبَيْرِ فَقَالَ هُمَا عُوَيْمُ بْنُ سَاعِدَةَ وَمَعْنُ بْنُ عَدِيٍّ
