Q: I am married and live with my husband & In-laws. My in-laws have invested certain amount of money with their son-in-law who have his own
trading firm and he pays a certain fix amount on monthly basis as return for investment. I would like to know whether this monthly fixed amount received on investment will be considered as halaal as per Islam.
A: If the investment is such that it generally has to be fixed, like rental on a property where the rental is fixed and very seldom it has any fluctuation then it is permissible. This is provided the nature of the investment is permissible and the workings of the investment are also permissible.
And Allah Ta’ala (الله تعالى) knows best.
