Section on the Qur’an and the Sunnah and the guidance they offer

As for the Book, it is this magnificent Qur’an—the speech of the Lord of all worlds. The Trustworthy Spirit brought it down upon the heart of Muhammad, the Messenger of Allah, peace and blessings be upon him, so that he might be among the warners. It came in a clear Arabic tongue, addressing all people with everything they need for the benefit of their religion and their worldly life. It is recited by tongues, written in codices, and safeguarded in hearts. Falsehood can never approach it, neither from before it nor from behind it; it is a revelation from One who is All-Wise, All-Praiseworthy.
