It's a metaphysical assumption, meaning beyond the realm of experimental science. Science has inherent limitations, and cannot be used to explain everything. This is a good starting point: https://www.youtube.com/watch?v=If3cNUixEBM

How did I know before I clicked that link that it was going to be apologetics.

Faith is not a shortcut to knowledge. "Hey, we can't yet find the answer to big questions through rational means, so let's try irrational means!"

You can throw around words like "apolegetics", but that doesn't make it less correct.

Islam has proof and evidence (e.g. http://provingislam.com, https://www.youtube.com/watch?v=nTsEZXx8kRg, https://www.reddit.com/r/islam/comments/hxn276/here_are_some..., and much more). Don't present a false dichotomy between science and faith where there isn't any for us in Islam.

Interesting how you just said science "cannot be used to explain everything" and yet now you're claiming "proof" and "evidence" (i.e. science) for your particular religion. Make up your mind.
