Be generous with your gifts; don't take them away from people once you have given them away; respect others' feelings when giving or taking something away from them; show gratitude for what you receive.

This hadith is about the comparison between taking back a gift and the behavior of a dog. The Prophet Muhammad ﷺ said that someone who takes back their gift is like a dog that eats until it is full, vomits, and then goes back to eat its vomit again. This hadith teaches us that taking back gifts can be seen as an act of greediness or selfishness. It also shows us how important it is to be generous with our gifts and not take them away from people once we have given them away. We should also remember that if we do take something away from someone, they may feel hurt or betrayed by our actions.
