Inherently there is nothing wrong in the whole concept of Insurance. Activity of Insurance is primarily a permissible activity. Insurance is a sort of contract for mutual help in which people pay a fixed amount in installments. The purpose is that if any of them is inflicted with losses relating to their persons or their wealth, they are compensated from this pooled money in a prescribed manner. Insurance involves use of complex actuarial estimates on happening / non-happening of insurance triggering events and frequency of such happenings which give an estimate on how much will be expended on insurance claims.
Instances where primary activity of an organization is Halal but it also earns interest through term deposits in a bank or other investements in banks as part of its financial management plan, this would not render the primary activity prohibited unless the insurance company explicitly states or mentions that insurance claims would be paid out of interest income solely.
