2.104 . O ye who believe , say not ( unto the Prophet ) : "Listen to us" but say "Look upon us , " and be ye listeners . For disbelievers is a painful doom .
Narated By 'Umar bin Al-Khattab : I gave a horse in Allah's Cause. The person to whom it was given, did not look after it. I intended to buy it from him, thinking that he would sell it cheap. When I asked the Prophet he said, "Don't buy it, even if he gives it to you for one Dirham, as the person who takes back what he has given in charity, is like a dog that swallows back its vomit."
