Narrated ‘Umar ibn al-Khattaab (may Allah be pleased with him): Once I gave a horse in Allah's Cause (in charity) but that person did not take care of it. I intended to buy it, as I thought he would sell it at a low price. So, I asked the Prophet ﷺ about it. He ﷺ said, "Neither buy, nor take back your alms which you have given, even if the seller were willing to sell it for one Dirham, for he who takes back his alms is like the one who swallows his own vomit.".
Commentary :
Giving in charity for the sake of Allah, Exalted be He, is considered one of the best and most rewarding good deeds. It necessitates that when a person gives something in charity hoping for its reward and blessings from Allah alone that he does not wish to have it back again or request that it goes back to his possession.
In this hadeeth, ‘Umar ibn al-Khataab (may Allah be pleased with him) reports that he gave a horse in charity and gifted to a man to use it in fighting in the cause of Allah. However, the man did not look after the horse properly and did not feed him enough or send it to gaze until it has become so weak. ‘Umar wished to buy it because he thought the man will sell it for a low price, so he (may Allah be pleased with him) consulted the Prophet ﷺ about his plan. The Prophet ﷺ ordered him not to proceed with his plan and not to retrieve his charity through buying or any other way, even if it will be sold for one Dirham i.e., he ﷺ told him not to desire it back at all or be tempted by its low price, and only view it as the charity that you have already given away because whoever takes back his charity is like a person who has vomited and then swallowed it! It is for this reason; it is considered so ugly for a person to give something in charity then retrieve it in any way. In another version of the report, in Saheeh al-Bukhaaree and Saheeh Muslim, it reads: “like a dog who swallows his own vomit” where he ﷺ gave this strong example to show the ugliness of this act and to discourage people from it.
This hadeeth shows us that we are ordered against taking back our charity or gifts, and that if one gives in charity something to a poor person, then the poor person needed to sell it, the charity giver should not buy it from him..
