>>103794OP here. That’s what is known as an ahaat, a sort of nasheed that doesn’t have vocals, and nowadays that is commonly used as a background tune, in this case, this one being used as a prominent background tune for the ISIS documentary “The Rise of the Khilafah and The Return of the Gold Dinar”. There was no official upload of this ahaat ever, but I do have a very rare version of it that is clean of any background noise. Here you go.
