Umar bin Khattab (RA) reported: I donated a pedigree horse in the path of Allah. Its possesser made it languish. I thought that he would sell it at a cheap price. I asked Allah's Messenger ( صلی اللہ علیہ وسلم ) about it, whereupon he said: Don't buy it and do not get back your charity, for one who gets back the charity is like a dog who swallows its vomit.

This hadith has been narrated on the authority of Malik bin Anas with the same chain of transmitters but with this addition: "Don't buy that even if he gives you for one dirham."

Zaid bin Aslam reported on the authority of his father that 'Umar (RA) donated a horse in the path of Allah. He found that it had languished in the hand of its possessor, and he was a man of meagre resources He (Hadrat 'Umar) intended to buy it. He came to Allah's Messenger ( صلی اللہ علیہ وسلم ) and made a mention of that to him, whereupon he said: Don't buy that even if you get it for a dirham for he who gets back the charity is like a dog which swallows its vomit.

This hadith has been narrated on the authority of Zaid bin Aslam with the same chain of transmitters but with this (change) that the hadith transmitted on the authority of Malik and Rauh (he was the son of Qisirn) is more complete and lengthy.
