(2) بَاب تَحْرِيمِ الرُّجُوعِ فِي الصَّدَقَةِ وَالْهِبَةِ بَعْدَ الْقَبْضِ إِلَّا مَا وَهَبَهُ لِوَلَدِهِ وَإِنْ سَفَلَ
Abdullah b. Tawus reported on the authority of his father who reported from Ibn Abas (Allah be pleased with them) who reported from Allah's Messenger 'may peace be upon him) that he said:
One who gets back his gift is like a dog which vomits and then swallows that vomit.
