What is meant by "the Book" mentioned in verses (38-40) of Surat An-Naml? Is it religious or worldly knowledge? And is it possible that this Book still exists to this day?

Summary: (He who had knowledge of the Scripture) was a righteous man from among humans, said to be "Asif ibn Barkhiya." He knew Allah's Greatest Name (Ism al-A'dham), and when he invoked Allah with it, Allah answered him. So, the angels carried the throne and brought it to Sulaiman. Interpreters differed regarding the meaning of "the Scripture." Some said it was a revealed book from Allah, like the Torah or the Zabur, or a specific book belonging to Sulaiman, or the books that contained wisdom. The intent is that this knowledge was not from worldly science books or remote control.
