Is it permissible, Islamically, to invest a sister's money, which was entrusted as an amanah (trust), by purchasing lands for investment purposes, with a guarantee of the principal and its return upon request or need, especially since the profits are good and the financial situation is difficult?
The agent acts according to what the principal has authorized him to do, and he is not permitted to exceed the limits of his agency. Placing the money in the bank without the owner's permission, or taking it and spending it for the agent's own needs, is impermissible and unlawful (haram).
