It is narrated from Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "The likeness of one who asks for the return of what he gifted is that of a dog which vomits and then eats its vomit. So when the giver asks for it back, let him be made to stand and be made known for what he has taken back; then let what he gifted be handed over to him."
