The Prophet (ﷺ) said, "The bad example is not for us. He who takes back his present is like a dog that swallows back its vomit."
Narrated `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 (ﷺ) 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."
Narrated Asma' bint Abu Bakr (ra)
My mother came to me during the lifetime of Allah's Messenger (ﷺ) and she was a Mushrikah (polytheist, idolatress, pagan). I said to Allah's Messenger (ﷺ) (seeking his verdict), "My mother has come to and she desires to recieve a reward from me, shall I keep good relations with her ?" The Prophet (ﷺ) said, "Yes, keep good relation with her."
