عَن عوفِ بْنِ مَالِكٍ: أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ إِذَا أَتَاهُ الْفَيْءُ قَسَمَهُ فِي يَوْمِهِ فَأَعْطَى الْآهِلَ حَظَّيْنِ وَأَعْطَى الْأَعْزَبَ حَظًّا فَدُعِيتُ فَأَعْطَانِي حَظَّيْنِ وَكَانَ لِي أَهْلٌ ثُمَّ دُعِيَ بَعْدِي عَمَّارُ بْنُ يَاسِرٍ فَأُعْطِيَ حَظًّا وَاحِدًا. رَوَاهُ أَبُو دَاوُد
