Abdullah bin 'Amr bin al-'Aas · Wages (Kitab Al-Ijarah)

"Or one of them tells the other: "Exercise the right."

Hakim asked (the Prophet): Messenger of Allah, a man comes to me and wants me to sell him something which is not in my possession. Should I buy it for him from the market? He replied: Do not sell what you do not possess.

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.

On his father's authority, said that his grandfather reported the Messenger of Allah (ﷺ) as saying: It is not permissible for a woman to present a gift from the property which she has in her possession when her husband owns her chastity.
