أَخْبَرَنَا مَحْمُودُ بْنُ خَالِدٍ، قَالَ حَدَّثَنَا عُمَرُ، عَنِ الأَوْزَاعِيِّ، قَالَ حَدَّثَنِي مُحَمَّدُ بْنُ عَلِيِّ بْنِ حُسَيْنٍ، قَالَ حَدَّثَنِي سَعِيدُ بْنُ الْمُسَيَّبِ، قَالَ حَدَّثَنِي عَبْدُ اللَّهِ بْنُ عَبَّاسٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ مَثَلُ الَّذِي يَرْجِعُ فِي صَدَقَتِهِ كَمَثَلِ الْكَلْبِ يَرْجِعُ فِي قَيْئِهِ فَيَأْكُلُهُ ‏"‏ ‏.‏
