"The Messenger of Allah said: 'No one should take back his gift except a father (taking back a gift) from his son. The one who takes back his gift is like one who goes back to his vomit.'" (Using translation from Nasāʾī 3689)
قَالَ رَسُولُ اللهِ ﷺ «لَا يَرْجِعُ أَحَدٌ فِي هِبَتِهِ إِلَّا وَالِدٌ مِنْ وَلَدِهِ وَالْعَائِدُ فِي هِبَتِهِ كَالْعَائِدِ فِي قَيْئِهِ»
