What is the Sharia ruling on a young man traveling to seek knowledge and improve his future without his parents' knowledge, given his difficult family circumstances that prevent him from achieving this within his country?

A father may take from his son’s wealth what he needs, without extravagance or causing harm to the son, as the Prophet, peace and blessings be upon him, said: “You and your wealth belong to your father,” provided that the father is not extravagant and does not harm the son. It is not permissible for a husband to take his working wife's money except with her consent. It is permissible for a child to travel for work or study without the parents' permission if the travel is safe and there is no fear of the parents being neglected. There is no obedience to the father in borrowing with usury.
