Isaiah 29:12

And the book is delivered to him that is not learned, saying read this, I pray thee: and he saith, I am not learned."

Comment: This Biblical verse refers to the unlettered prophet, Muhammad, peace be upon him. God alone was his teacher Who taught him through revelation. God said: "No does he say (aught) of (his own) Desire. It is no less than inspiration sent down to him: He was taught by one Mighty in Power." (Qur'an 53:3-5).
