"It is not permissible for anyone to give a gift then take it back, except a father." Tawus said: "I used to hear the boys say: 'O you who goes back to his vomit!' But I did not realize that the Messenger of Allah had said this as a parable, until we heard that he used to say: 'The likeness of the one who gives a gift then takes it back, is that of the dog which eats its vomit.'"  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ يَحِلُّ لأَحَدٍ يَهَبُ هِبَةً ثُمَّ يَعُودُ فِيهَا إِلاَّ الْوَالِدَ قَالَ طَاوُسٌ كُنْتُ أَسْمَعُ الصِّبْيَانَ يَقُولُونَ يَا عَائِدًا فِي قَيْئِهِ وَلَمْ أَشْعُرْ أَنَّ رَسُولَ اللَّهِ ﷺ ضَرَبَ ذَلِكَ مَثَلاً حَتَّى بَلَغَنَا أَنَّهُ كَانَ يَقُولُ مَثَلُ الَّذِي يَهَبُ الْهِبَةَ ثُمَّ يَعُودُ فِيهَا وَذَكَرَ كَلِمَةً مَعْنَاهَا كَمَثَلِ الْكَلْبِ يَأْكُلُ قَيْئَهُ  

"The Messenger of Allah said: 'It is not permissible for anyone to give a gift then take it back, except from one's son.'" 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." (Using translation from Nasāʾī 3692)  

قَالَ رَسُولُ اللهِ ﷺ «لَا يَحِلُّ لِأَحَدٍ أَنْ يَهَبَ هِبَةً ثُمَّ يَرْجِعَ فِيهَا إِلَّا مِنْ وَلَدِهِ» قَالَ طَاوُسٌ كُنْتُ أَسْمَعُ وَأَنَا صَغِيرٌ «عَائِدٌ فِي قَيْئِهِ» لَمْ أَكُنْ أَظُنُّ أَنَّهُ ضَرَبَ لَهُ مَثَلًا قَالَ «فَمَنْ فَعَلَ ذَلِكَ فَمَثَلُهُ كَمَثَلِ الْكَلْبِ يَأْكُلُ ثُمَّ يَقِيءُ ثُمَّ يَعُودُ فِي قَيْئِهِ»
