That's objectively not true. The reason religion talks about virtue and sin so much is because it's understood that each person has the power to chose one or the other. That's the fundamental free will, all stems from it.
I don't think that's the (main) reason that religions focuses on virtue and sin, but that's kind of to one side.
Free will does suggest that all prophets are making educated guesses, rather than receiving divine insight into future events. In Christian mythology there's the classic Matthew 26:21 bit that atheists like to point out in any discussion about free will (or lack of).
I don't have any insight into the texts of the other two large organised religions, but I'm sure there's a some number of distant predictions in those that stretch the 'everyone has free will' claim.
That's quite the stretch.
Most of the largest pseudo-monotheistic mythologise effectively preclude free will by virtue of their various predestination fables.
