"The parable of the one who gives a gift, and then takes it back, is that of a dog who eats until he is full, and vomits, then he returns to [take back] his vomit."
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ مَثَلُ الَّذِي يُعْطِي الْعَطِيَّةَ ثُمَّ يَرْجِعُ فِيهَا كَالْكَلْبِ أَكَلَ حَتَّى إِذَا شَبِعَ قَاءَ ثُمَّ عَادَ فَرَجَعَ فِي قَيْئِهِ
