Ibn Majah

"Bear witness that I have given Nu'man such and such from my wealth." He said: "Have you given all your children something like that which you have given to Nu'man?" He said: "No." He said: "Then let someone other than me bear witness to that." And he said: "Would you not like all your children to honor you equally?" He said: "Of course." He said: "Then do not do this."

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)."

"It is not permissible for a man to give a gift then take it back, except what a father gives to his child."

"None of you should take back his gift, except a father (taking it back) from his son."

"There is no lifelong grant. Whoever is given something as a lifelong grant, it is his.' "

"I heard the Messenger of Allah (ﷺ) say: 'Whoever gives a lifelong grant to a man, it belongs to him (the recipient) and to his heirs. His (the giver's) words put an end to his right to it, and it belongs to the one to whom it was given for life and to his heirs."

the Prophet (ﷺ) ruled that a gift given for life belongs to the heirs (of the recipient).

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

"Umra belongs to the one to whom it is given, and Ruqba belongs to the one to whom it is given."

"The likeness of one who takes back his gift is that of a dog that eats until it is full and vomits; then it goes back to its vomit and eats it again."

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

"The one who takes back his gift is like the dog that goes back to its vomit."

"A man has more right to his gift so long as he has not gotten something in return for it."

"It is not permissible for a woman to dispose of her wealth except with her husband's permission, once he has married her."

his grandmother Khairah, the wife of Ka'b bin Malik, came to the Messenger of Allah (ﷺ) with some jewelry belonging to her and said, I am giving this in charity. The Messenger of Allah (ﷺ) said to her: "It is not permissible for a woman to dispose of her wealth without her husband's permission. Did you ask Ka'b's permission?" She said: "Yes." So the Messenger of Allah (ﷺ) sent for Ka'b bin Malik, her husband, and said, "Did you give Khairah permission to give her jewelry in charity?" He said: "Yes." So the Messenger of Allah (ﷺ) accepted it from her.
