Father investing his child’s money

From the outset, it should be borne in mind that having children is a great bounty of Allah Ta’ala, and a trust from Him. Hence, one should take care of this bounty to the best of one’s ability. Together with attending to the physical well-being, Deeni education, and spiritual upbringing of one’s children, it is also important to take care of their wealth and belongings. This requires that one invests their funds in the best of avenues.

Now coming to the query, if investing in gold seems to be a profitable venture which will benefit the child, then the father may invest his child’s money in gold, since he has the authority to make decisions and transact in his child wealth.
