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

Ibn ‘Umar told that he saw the first thing God’s Messenger did immediately anything came to him was to give something to those who had been set free. Abu Dawud transmitted it.
