The Prohibition Of Taking Back One's Charity After It Has Been Accepted, Except In The Case Of What A Father Gives To A Son Or Grandson
وَحَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، أَخْبَرَنَا الْمَخْزُومِيُّ، حَدَّثَنَا وُهَيْبٌ، حَدَّثَنَا عَبْدُ اللَّهِ، بْنُ طَاوُسٍ عَنْ أَبِيهِ، عَنِ ابْنِ عَبَّاسٍ، عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم قَالَ " الْعَائِدُ فِي هِبَتِهِ كَالْكَلْبِ يَقِيءُ ثُمَّ يَعُودُ فِي قَيْئِهِ " .
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 (ﷺ) '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.
