A book that can train prophets

Qur'an is a book that can train Prophets, for Prophets are of two kinds:

Those that are designated to Prophethood by God,

And the ‘Prophets of Perfection’ that acquire the perfections of the prophets as a result of their beliefs, and acting upon the commands of the Qur’an. Based on this, the Qur’an trains prophets of perfection.
