Mishkat al-Masabih
He said that God’s Messenger used to give a quarter as booty after the fifth had been kept off, and a third after the fifth had been kept off when he returned. Abu Dawud transmitted it.
وَعَنْهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ يُنَفِّلُ الرُّبُعَ بَعْدَ الْخُمُسِ وَالثُّلُثَ بَعْدَ الْخُمُسِ إِذَا قَفَلَ. رَوَاهُ أَبُو دَاوُدَ
