Answer
(Fatwa: 216/180/H=1434)
It is unlawful to produce HRA fraudulently, it is sinful. If you are living in your parents’ house, there is no issue if you have dealing of rent with your parents in clear terms, and then you get tax exception on HRA basis. It is allowable for you to have rental dealing with your parents.
(N) It is also lawful to resort to life insurance in order to avert taxation, but one will have to give the additional amount in charity to the poor without an intention of reward. It should not be used in personal needs.
