What is the ruling on real estate REITs?

The ruling on contributing to Real Estate Investment Trusts (REITs) depends on two conditions: that the investment field is in permissible real estate, and that the institution does not borrow with usury or deposit its funds in usurious accounts. The details of the real estate institution's activities and its financial statements must be examined to determine if it deals with usury. Contributing to companies that deal with usury is forbidden, and if a contributor becomes aware of this, they must withdraw from it.
