حَدَّثَنَا أَبُو الْيَمَانِ، أَخْبَرَنَا شُعَيْبٌ، عَنِ الزُّهْرِيِّ، قَالَ أَخْبَرَنِي عَبْدُ اللَّهِ بْنُ عَامِرِ بْنِ رَبِيعَةَ، وَكَانَ، مِنْ أَكْبَرِ بَنِي عَدِيٍّ وَكَانَ أَبُوهُ شَهِدَ بَدْرًا مَعَ النَّبِيِّ صلى الله عليه وسلم أَنَّ عُمَرَ اسْتَعْمَلَ قُدَامَةَ بْنَ مَظْعُونٍ عَلَى الْبَحْرَيْنِ، وَكَانَ شَهِدَ بَدْرًا، وَهُوَ خَالُ عَبْدِ اللَّهِ بْنِ عُمَرَ وَحَفْصَةَ رضى الله عنهم‏.‏
