"Some of those who met the Prophet told us that he said: 'The likeness of the one who gives (something), then takes back his gift, is that of a dog which eats, then vomits, then eats its vomit.'" (Using translation from Nasāʾī 3705)
حَدَّثَنَا بَعْضُ مَنْ أَدْرَكَ النَّبِيَّ ﷺ أَنَّهُ قَالَ «مَثَلُ الَّذِي يَهَبُ فَيَرْجِعُ فِي هِبَتِهِ كَمَثَلِ الْكَلْبِ يَأْكُلُ فَيَقِيءُ ثُمَّ يَأْكُلُ قَيْئَهُ»
"Some of those who met the Prophet told us that he said: 'The likeness of the one who gives (something), then takes back his gift, is that of a dog which eats, then vomits, then eats its vomit.'"
أَخْبَرَنَا بَعْضُ مَنْ أَدْرَكَ النَّبِيَّ ﷺ أَنَّهُ قَالَ مَثَلُ الَّذِي يَهَبُ فَيَرْجِعُ فِي هِبَتِهِ كَمَثَلِ الْكَلْبِ يَأْكُلُ فَيَقِيءُ ثُمَّ يَأْكُلُ قَيْئَهُ
“The likeness of one who takes back his gift is that of a dog that eats until it is full and vomits; then it goes back to its vomit and eats it again.” (Using translation from Ibn Mājah 2384)
قَالَ رَسُولُ اللهِ ﷺ مَثَلُ الَّذِي يَعُودُ فِي هِبَتِهِ كَمَثَلِ الْكَلْبِ أَكَلَ حَتَّى إِذَا شَبِعَ قَاءَ ثُمَّ عَادَ فِي قَيْئِهِ فَأَكَلَهُ
