أَخْبَرَنَا مُحَمَّدُ بْنُ حَاتِمٍ، قَالَ حَدَّثَنَا حِبَّانُ، قَالَ أَنْبَأَنَا عَبْدُ اللَّهِ، عَنْ إِبْرَاهِيمَ بْنِ نَافِعٍ، عَنِ الْحَسَنِ بْنِ مُسْلِمٍ، عَنْ طَاوُسٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ لاَ يَحِلُّ لأَحَدٍ أَنْ يَهَبَ هِبَةً ثُمَّ يَرْجِعَ فِيهَا إِلاَّ مِنْ وَلَدِهِ ‏"‏ ‏.‏ قَالَ طَاوُسٌ كُنْتُ أَسْمَعُ وَأَنَا صَغِيرٌ عَائِدٌ فِي قَيْئِهِ فَلَمْ نَدْرِ أَنَّهُ ضَرَبَ لَهُ مَثَلاً قَالَ ‏"‏ فَمَنْ فَعَلَ ذَلِكَ فَمَثَلُهُ كَمَثَلِ الْكَلْبِ يَأْكُلُ ثُمَّ يَقِيءُ ثُمَّ يَعُودُ فِي قَيْئِهِ ‏"‏ ‏.‏

Tawus said: "When I was young I used to hear (the phrase), 'The one who goes back to his vomit,' but we did not realize that this was a similitude." He said: "The likeness of the one who does that is that of a dog which eats then vomits, then goes back to its vomit
