حَدَّثَنَا أَبُو الْيَمَانِ، أَخْبَرَنَا شُعَيْبٌ، عَنِ الزُّهْرِيِّ، ح وَقَالَ اللَّيْثُ حَدَّثَنِي عَبْدُ الرَّحْمَنِ بْنُ خَالِدٍ، عَنِ ابْنِ شِهَابٍ، عَنْ عُبَيْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ بْنِ عُتْبَةَ بْنِ مَسْعُودٍ، أَنَّ أَبَا هُرَيْرَةَ ـ رضى الله عنه ـ قَالَ قَالَ أَبُو بَكْرٍ ـ رضى الله عنه ـ وَاللَّهِ لَوْ مَنَعُونِي عَنَاقًا كَانُوا يُؤَدُّونَهَا إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم لَقَاتَلْتُهُمْ عَلَى مَنْعِهَا. قَالَ عُمَرُ ـ رضى الله عنه ـ فَمَا هُوَ إِلاَّ أَنْ رَأَيْتُ أَنَّ اللَّهَ شَرَحَ صَدْرَ أَبِي بَكْرٍ ـ رضى الله عنه ـ بِالْقِتَالِ، فَعَرَفْتُ أَنَّهُ الْحَقُّ.
