In my current job on top of my basic salary, I have additional benefits that I am entitled to. What is the Shariah ruling on accepting the following benefits? a). Free medical insurance - I am eligible for this scheme in the eventuality of any illness? b). A non-contributory pension scheme / pension supplement ? the company contributes up to a certain percentage of my annual salary to a pension scheme or I am paid a certain percentage of my annual salary as a cash pension supplement? c). Free life cover ? The company provides free life cover to my dependants if I was to die before the age of 65 (a one off payment to any named dependants up to 4 times the salary if I die before the age of 65)? d). Free Permanent Health Insurance - The company provide free cover to continue paying a major proportion of my salary if for some reason I was away from work for a long period of time (major accident, long term illness etc?)? (Please note that all the benefits provided are run by conventional insurance and pension companies on behalf of my firm)
