عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ مَثَلُ الَّذِي يَعُودُ فِي عَطِيَّتِهِ كَمَثَلِ الْكَلْبِ يَأْكُلُ حَتَّى إِذَا شَبِعَ قَاءَ ثُمَّ عَادَ فِي قَيْئِهِ فَأَكَلَهُ
Narrated by Sayyiduna Abu Huraira (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: The example of a person who takes back his gift is like that of a dog who keeps eating until he is full, then vomits, and then starts licking his own vomit.
