Sunan an-Nasa'i, Book 32, Hadith 16 (In-Book) ⓘ

It was narrated from 'Amr bin Shu'aib, from Tawus, from Ibn 'Umar and Ibn 'Abbas, that they said: "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.'"

أَخْبَرَنَا عَبْدُ الرَّحْمَنِ بْنُ مُحَمَّدِ بْنِ سَلاَّمٍ، قَالَ حَدَّثَنَا إِسْحَاقُ الأَزْرَقُ، قَالَ حَدَّثَنَا بِهِ، حُسَيْنٌ الْمُعَلِّمُ عَنْ عَمْرِو بْنِ شُعَيْبٍ، عَنْ طَاوُسٍ، عَنِ ابْنِ عُمَرَ، وَابْنِ، عَبَّاسٍ قَالاَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ لاَ يَحِلُّ لأَحَدٍ أَنْ يُعْطِيَ الْعَطِيَّةَ فَيَرْجِعَ فِيهَا إِلاَّ الْوَالِدَ فِيمَا يُعْطِي وَلَدَهُ وَمَثَلُ الَّذِي يُعْطِي الْعَطِيَّةَ فَيَرْجِعُ فِيهَا كَالْكَلْبِ يَأْكُلُ حَتَّى إِذَا شَبِعَ قَاءَ ثُمَّ عَادَ فَرَجَعَ فِي قَيْئِهِ ‏" ‏ ‏.‏
