The Prophet ﷺ said, "One who takes back his gift (which he has already given) is like a dog that swallows its vomit." (Using translation from Bukhārī 2589)  

عَنْ رَسُولِ اللهِ ﷺ قَالَ «الْعَائِدُ فِي هِبَتِهِ كَالْكَلْبِ يَقِيءُ ثُمَّ يَعُودُ فِي قَيْئِهِ»  

The Prophet ﷺ said, "He who takes back his present is like him who swallows his vomit." (Using translation from Bukhārī 2621)  

قَالَ رَسُولُ اللهِ ﷺ «الْعَائِدُ فِي هِبَتِهِ كَالْعَائِدِ فِي قَيْئِهِ»  

"The Messenger of Allah said: 'It is not permissible for anyone to give a gift then take it back, except a father with regard to what he gives to his son. The likeness of the one who gives a gift then takes it back, is that of the dog which eats then when it is full it vomits, then it goes back to its vomit.'" (Using translation from Nasāʾī 3703)  

قَالَ رَسُولُ اللهِ ﷺ «لَا يَحِلُّ لِأَحَدٍ يُعْطِي الْعَطِيَّةَ فَيَرْجِعَ فِيهَا إِلَّا الْوَالِدَ فِيمَا يُعْطِي وَلَدَهُ وَمَثَلُ الَّذِي يُعْطِي الْعَطِيَّةَ فَيَرْجِعُ فِيهَا كَالْكَلْبِ أَكَلَ حَتَّى إِذَا شَبِعَ قَاءَ ثُمَّ عَادَ فَرَجَعَ فِي قَيْئِهِ»  

"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.'" (Using translation from Nasāʾī 3704)  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ «لَا يَحِلُّ لِأَحَدٍ يَهَبُ هِبَةً يَعُودُ فِيهَا إِلَّا الْوَالِدَ» قَالَ طَاوُسٌ كُنْتُ أَسْمَعُ الصِّبْيَانَ يَقُولُونَ يَا عَائِدًا فِي قَيْئِهِ وَلَمْ أَشْعُرْ أَنَّ رَسُولَ اللهِ ﷺ ضَرَبَ ذَلِكَ مَثَلًا حَتَّى بَلَغَنَا أَنَّهُ كَانَ يَقُولُ «مَثَلُ الَّذِي يَهَبُ الْهِبَةَ ثُمَّ يَعُودُ فِيهَا» وَذَكَرَ كَلِمَةً مَعْنَاهَا «كَمَثَلِ الْكَلْبِ يَأْكُلُ قَيْئَهُ»  

"Some of those who met the Prophet told us that he said: 'The likeness of the one who gives (something), then takes back his gift, is that of a dog which eats, then vomits, then eats its vomit.'" (Using translation from Nasāʾī 3705)  

حَدَّثَنَا بَعْضُ مَنْ أَدْرَكَ النَّبِيَّ ﷺ أَنَّهُ قَالَ «مَثَلُ الَّذِي يَهَبُ فَيَرْجِعُ فِي هِبَتِهِ كَمَثَلِ الْكَلْبِ يَأْكُلُ فَيَقِيءُ ثُمَّ يَأْكُلُ قَيْئَهُ»
