The Prophet ﷺ said, "He who takes back his present is like him who swallows his vomit."  

قَالَ النَّبِيُّ ﷺ الْعَائِدُ فِي هِبَتِهِ كَالْعَائِدِ فِي قَيْئِهِ  

The Prophet ﷺ said, "The bad example is not for us. He who takes back his present is like a dog that swallows back its vomit."  

قَالَ النَّبِيُّ ﷺ لَيْسَ لَنَا مَثَلُ السَّوْءِ الَّذِي يَعُودُ فِي هِبَتِهِ كَالْكَلْبِ يَرْجِعُ فِي قَيْئِهِ  

I gave a horse in Allah's Cause. The person to whom it was given, did not look after it. I intended to buy it from him, thinking that he would sell it cheap. When I asked the Prophet ﷺ he said, "Don't buy it, even if he gives it to you for one Dirham, as the person who takes back what he has given in charity, is like a dog that swallows back its vomit."  

عَنْ ذَلِكَ النَّبِيَّ ﷺ فَقَالَ لاَ تَشْتَرِهِ وَإِنْ أَعْطَاكَهُ بِدِرْهَمٍ وَاحِدٍ فَإِنَّ الْعَائِدَ فِي صَدَقَتِهِ كَالْكَلْبِ يَعُودُ فِي قَيْئِهِ
