Is my work in a real estate company, which involves preparing documents and promoting the sale of apartments and lands in installments through usurious banks, unlawful (haram)?

Allah Almighty has forbidden transactions that involve harm or injustice, such as usurious contracts. Means are subject to the rulings of their ends, and anything that leads to the forbidden is forbidden, for Allah Almighty says: "And cooperate in righteousness and piety, but do not cooperate in sin and aggression." Forbidden things become permissible out of genuine necessity. Installment sales through financing from a usurious bank (where the bank pays the value of the property and then resells it to the client in installments with an increase) is a forbidden transaction; it is a usurious loan, and aiding in usury is impermissible. Therefore, it is not permissible to continue working in a job based on this usurious transaction except in a situation of extreme necessity where one cannot find a means to live, along with the obligation to search for another permissible job. Women's work is permissible if it is free from prohibitions and adheres to legitimate Islamic guidelines.
