Those who said he may take from his child's wealth only with the child's permission

Ibn Sirin (may Allah have mercy on him) said that it is necessary for a child to treat his father well, and that every person has the greater right to what he owns.

It is narrated from Ibn Awn that a man asked al-Qasim bin Muhammad: "May a person (a father) use whatever he wishes from his son's wealth without permission?" He said: "I do not know what this is."

Mujahid said: "Take from your son's wealth what you gave him, and do not take what you did not give him."

It is narrated from Salim that Hamzah bin Abdullah bin Umar slaughtered a camel. A beggar asked Sayyiduna Ibn Umar (may Allah be pleased with them both) for something. Sayyiduna Abdullah said: "This is not my wealth." Hamzah said: "Father, it is lawful for you too. You may feed from it whomever you wish."

Al-Zuhri said that if a father is in need, he may spend from his child's wealth only as much as he spent on him.

Sayyiduna Ali (may Allah be pleased with him) said that if a son is young, the father has the greater right to his wealth. When the son grows up and separates his wealth, then the son has the greater right to it.
