What is the ruling on saving in European companies specialized in retirement pensions, by paying a monthly sum and investing it in stocks to obtain a fixed pension after the age of sixty, and a lump sum for the family after death?

This transaction is impermissible due to its inclusion of several শরীʿআ (Sharia) prohibitions, such as: ignorance (جهالة) and gharar (غرر - excessive uncertainty), the companies investing their money in interest-based (riba) transactions and not adhering to what is permissible (حلال), and because it is a loan that draws benefit to the borrower, rather than a sound mudarabah (profit-sharing) contract.
