English translation
1490. Narrated 'Umar رَضِيَ اللَّهُ عَنْهُ: Once I gave a horse in Allâh'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 said, "Neither buy, nor take back your alms which you have given, even if it is given to you (or 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."
