Question - Is it permissible to use interest money to build a toilet for one’s own use? I have received a substantial amount of interest from the bank, therefore I would like to know if I may use this money to build a toilet. Answer - It is not permissible to use interest money or any other Haraam money for one’s own requirements. You may therefore NOT build a toilet with such money. You shall have to give the unlawful money to the poor without making any Niyyat of Sawaab. It is obligatory to eliminate all Haraam wealth in one’s possession.
