(Second chain) Sayyiduna Umar bin Khattab (may Allah be pleased with him) says: I gave a horse in charity in the way of Allah during the time of the Messenger of Allah (peace and blessings be upon him), but its owner wasted it, so I intended to buy it back, while I also expected that he would sell it to me at a cheap price. Then I thought that I should first ask the Messenger of Allah (peace and blessings be upon him) about this. He (peace and blessings be upon him) said: Do not buy it, even if he gives it to you in exchange for one dirham. The example of one who takes back what he has given in charity is like a dog that vomits and then licks it up.
