“It is not permissible for a man to give a gift then take it back, except what a father gives to his child.”  

عَنِ ابْنِ عَبَّاسٍ وَابْنِ عُمَرَ يَرْفَعَانِ الْحَدِيثَ إِلَى النَّبِيِّ ﷺ قَالَ لاَ يَحِلُّ لِلرَّجُلِ أَنْ يُعْطِيَ الْعَطِيَّةَ ثُمَّ يَرْجِعَ فِيهَا إِلاَّ الْوَالِدَ فِيمَا يُعْطِي وَلَدَهُ  

“None of you should take back his gift, except a father (taking it back) from his son.”  

أَنَّ نَبِيَّ اللَّهِ ﷺ قَالَ لاَ يَرْجِعْ أَحَدُكُمْ فِي هِبَتِهِ إِلاَّ الْوَالِدَ مِنْ وَلَدِهِ
