The truthful religion and or its revealed scripture does not claims to be a text-book of science. Right?
Religion is a deeply personal matter. It is doubtful that a single religion can ever be truthful for many or most people, unless perhaps if it is highly customizable. Hinduism comes close, but even it would be under considerable stress to fill such an ambitious bill.
Revealed scrpiture is subject to similar considerations, except that of course it is by nature not very customizable at all.
There is
some overlap between science and religion, mostly when it comes to social duties, but not too much of it. It is difficult to imagine a scripture that would be very inovative from a scientific perspective, among other reasons because scripture can't learn from new research.
As for what any specific religion or scripture might claim to be, I don't think there are too many hard rules on that.
