أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ، ح وَأَخْبَرَنِي عَلِيُّ بْنُ حُجْرٍ، عَنْ إِسْمَاعِيلَ، عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ، عَنِ ابْنِ عُمَرَ، قَالَ كُنَّا نُبَايِعُ رَسُولَ اللَّهِ صلى الله عليه وسلم عَلَى السَّمْعِ وَالطَّاعَةِ ثُمَّ يَقُولُ " فِيمَا اسْتَطَعْتَ " . وَقَالَ عَلِيٌّ " فِيمَا اسْتَطَعْتُمْ " .
