Be generous with your gifts & donations without expecting anything in return .

This hadith explains that it is not permissible for someone to give something as a gift or donation and then take it back. This applies to all people except for fathers who are giving something to their children. The Prophet Muhammad likened this action to that of a dog which eats until it is full, vomits what it has eaten, but then goes back and eats the vomit again. This hadith teaches us that we should be generous with our gifts and donations without expecting anything in return; if we do expect something in return, we should not give the gift or donation at all.
