Euhm, which religion was dominant in the Byzantine Empire ? This illustrates what happened though: large (and I do mean LARGE) parts of the West had seriously damaged and/or eradicated science. But ... that wasn't the last part. And the remaining part did believe in science. That wouldn't have mattered at all if the knowledge was in only one location ... but because of the copying, it did matter. Only small parts of the knowledge were totally lost, even if they did disappear almost from all of western europe for quite a while. Oh, and to make matters even worse ... what was the dominant religion in Toledo in 1085 ? Not the rulers' religion ... the religion of the population ... (despite the constant muslim massacres I might add)
