Ruling on savings certificates with variable return from the Faisal Islamic Bank
Question

                What is the ruling on buying savings certificates with variable return from the Faisal Islamic Bank of Egypt? Please look at the bank’s website for more details.
Praise be to Allah.
      We do not know anything about the investment methods used 
      by the Faisal Islamic Bank. We have previously explained the shar‘i 
      guidelines on investment in the answer to question no.
      113852. 

    There is nothing on their website to explain the issue of 
    capital: is it guaranteed by the bank or not? And there is no information on 
    the share of profit which should be stated. In the answer referred to, we 
    explained that it is essential to state the rate of profit, such as 5% or 
    10% for example, from the profit and not from the capital. It is not valid 
    to invest or engage in mudaarabah if this rate is not stipulated in the 
    contract, contrary to what is commonly believed, that shar‘i investment is 
    that in which nothing is stipulated. 

    To sum up: If the conditions of valid investment are met in 
    this contract - which does not appear to us to be the case from their 
    website - then there is nothing wrong with entering into it. 

    And Allah knows best.
