Are the medical pension and financial entitlements from the Public Authority for Social Insurance and Pensions, which were deducted from the monthly salary of an employee working in a commercial bank, permissible (halal) or do they involve a doubtful aspect (shubha)?

Working in an interest-based bank is impermissible, and the wages earned from it are unlawful, because it constitutes aiding in sin and renting out a prohibited benefit. Neither the bank nor the employee owns these wages, as they are ill-gotten gains. This money should be spent on the welfare of Muslims, such as the poor and the needy. A poor and needy employee who has sincerely repented may take from this money an amount sufficient for his needs. There is no difference in this regard between regular salary and financial entitlements upon resignation.
