[M]Believe all revealed books are from Allah: Suhuf (scrolls of Ibrahim),
Tawrah (Torah to Musa), Zabur (Psalms to Dawud), Injil (Gospel to Isa),
and the Qur'an (final revelation to Muhammad ).
[M]Believe the Qur'an is the final, word-for-word preserved speech of Allah —
no letter has been changed. (Qur'an 15:9)
[M]Follow the rulings of the Qur'an — it abrogates all previous scriptures.
[1]Recite the Qur'an daily with proper tajweed. The Prophet said: "Recite the
Qur'an for it will come as an intercessor for its companions on the Day of
Judgment." (Muslim 804)
[2]Complete a full khatm (complete recitation) of the Qur'an at least annually.
[1]Reflect on its meanings (tadabbur) — it is a book of guidance, not just recitation.
