"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»
