Muhammad bin Yahya bin Hiban محمد بن يحيى بن حبان · The Chapters on Gifts

his father gave him a gift of a slave, and he came to the Prophet (ﷺ) so that he could witness the gift. He said: “Have you given something to all of your children?” He said: “No.” He said: “Then take back (your gift).”

“There is no Ruqba. Whoever is given a gift on the basis of Ruqba, it belongs to him, whether he lives or dies.”

“The one who takes back his gift is like the one who goes back to his vomit.”
