It was narrated from Abu Az-Zubair, from Tawus, that Ibn 'Abbas said:

"The Messenger of Allah said: 'The one who takes back his gift, is like the one who goes back to his vomit.'"

أَخْبَرَنَا أَحْمَدُ بْنُ حَرْبٍ، قَالَ حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنْ حَجَّاجٍ، عَنْ أَبِي الزُّبَيْرِ، عَنْ طَاوُسٍ، عَنِ ابْنِ عَبَّاسٍ، قَالَ قَالَ رَسُولُ اللَّهِ ﷺ " الْعَائِدُ فِي هِبَتِهِ كَالْعَائِدِ فِي قَيْئِهِ " .
