حَدَّثَنَا مُسْلِمُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا قُرَّةُ، حَدَّثَنَا عَمْرُو بْنُ دِينَارٍ، عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ ـ رضى الله عنهما ـ قَالَ بَيْنَمَا رَسُولُ اللَّهِ صلى الله عليه وسلم يَقْسِمُ غَنِيمَةً بِالْجِعْرَانَةِ إِذْ قَالَ لَهُ رَجُلٌ اعْدِلْ‏.‏ فَقَالَ لَهُ ‏"‏شَقِيتَ إِنْ لَمْ أَعْدِلْ ‏"
