حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ بْنِ قَعْنَبٍ، حَدَّثَنَا مَالِكُ بْنُ أَنَسٍ، عَنْ زَيْدِ بْنِ أَسْلَمَ، عَنْ أَبِيهِ، أَنَّ عُمَرَ بْنَ الْخَطَّابِ، قَالَ حَمَلْتُ عَلَى فَرَسٍ عَتِيقٍ فِي سَبِيلِ اللَّهِ فَأَضَاعَهُ صَاحِبُهُ فَظَنَنْتُ أَنَّهُ بَائِعُهُ بِرُخْصٍ فَسَأَلْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم عَنْ ذَلِكَ فَقَالَ ‏"‏ لاَ تَبْتَعْهُ وَلاَ تَعُدْ فِي صَدَقَتِكَ فَإِنَّ الْعَائِدَ فِي صَدَقَتِهِ كَالْكَلْبِ يَعُودُ فِي قَيْئِهِ ‏"‏ ‏.‏
Translation
Ibn 'Umar reported that 'Umar b. al-Khattib (Allah be pleased with him) donated a horse in the path of Allah and (later on) he found it being sold, and he decided to buy that. He asked the Messenger of Allah (ﷺ) about it. whereupon he (the Holy prophet) said

Don't buy that and do not get back what you gave in charity.

Comment

The Book of Gifts - Sahih Muslim 1621 a

This prohibition concerns the one who gives a gift and then seeks to reclaim it, except in the case of a father regarding what he gives to his child. The Prophet (peace be upon him) said: "One who takes back his gift is like a dog which vomits and then returns to its vomit." This illustrates the reprehensible nature of retracting charitable giving, as it nullifies the sincerity and reward of the initial act.

Scholarly Commentary

The prohibition against reclaiming gifts serves to protect the sanctity of charitable acts and maintain social harmony. A gift, once given, becomes the rightful property of the recipient, and seeking its return violates their established rights.

The exception for fathers reflects the unique nature of the parent-child relationship, where gifts often serve as ongoing family support rather than pure charity. However, even in this case, scholars recommend against reclaiming gifts to preserve family bonds.

This teaching emphasizes the importance of sincere intention in giving and warns against treating charity as a temporary loan or conditional transfer of property.
