What is the ruling on subscribing to a fund that deducts a monthly amount from the salary and grants a bonus upon retirement or death, knowing that its money is invested in purchasing government securities, stock market shares, real estate, loans to subscribers with interest, and usurious bank deposits?

It is not permissible for an employee to subscribe to this fund because its money is invested in what is forbidden. The one who consumes usury, the one who feeds it, and the one who assists in it are all equal in sin, due to the Prophet (peace and blessings be upon him) saying: "The Prophet (peace and blessings be upon him) cursed the one who consumes usury, the one who feeds it, its two witnesses, and its scribe, and he said: 'They are all equal (in sin).'" And due to his (peace and blessings be upon him) saying: "Indeed, the Holy Spirit inspired in my heart that no soul will die until it completes its term and receives its full provision. So, fear Allah and be graceful in seeking (your provision)."
