وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ مُحَمَّدِ بْنِ عَبْدِ اللَّهِ بْنِ عَبْدِ الرَّحْمَنِ بْنِ أَبِي صَعْصَعَةَ الأَنْصَارِيِّ، ثُمَّ الْمَازِنِيِّ عَنْ أَبِيهِ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏:‏ ‏"‏ لَيْسَ فِيمَا دُونَ خَمْسَةِ أَوْسُقٍ مِنَ التَّمْرِ صَدَقَةٌ، وَلَيْسَ فِيمَا دُونَ خَمْسِ أَوَاقِيَّ مِنَ الْوَرِقِ صَدَقَةٌ، وَلَيْسَ فِيمَا دُونَ خَمْسِ ذَوْدٍ مِنَ الإِبِلِ صَدَقَةٌ ‏"‏ ‏.‏
