Is it obligatory for a 16-year-old girl who has money given to her by some of her relatives to give this money to her father who spends on her?

If a father is in need, it is obligatory for a well-off son to spend on him. If he is not in need, it is better for the son to give his father money as an act of kindness and filial piety, based on the Almighty's saying: "And your Lord has decreed that you worship none but Him. And to parents, show goodness" [Al-Isra: 23]. Your father has the right to take from your money as much as he needs without your permission, based on the Prophet's (peace and blessings be upon him) saying: "You and your wealth belong to your father."
