Usamah ibn Zayd · Wages (Kitab Al-Ijarah)

The Prophet (ﷺ) said: It is not lawful for a man to make a donation or give a gift and then take it back, except a father regarding what he gives his child. One who gives a gift and then takes it back is like a dog which eats and vomits when it is full, then returns to its vomit.
