How can Islamic creed be established in our souls to demolish the creed of Jahiliyyah, and should we follow the methodology of the Quran in its revelation to study creed from it, and are there books that achieve this purpose?

The questioner is correct that the Noble Qur’an is the best means to what he seeks, for through it, the servant comes to know and love his Lord, and it is the foundation of faith that bears righteous deeds. This Ummah will not return to the right path unless the Qur’an becomes the source of its reception, the methodology of its life, and the path to its revival. Many contemporary scholars have given attention to this topic, among them Dr. Muhammad Bazmul and Ustadh Majdi Al-Hilali, and there is a beneficial lecture by Sheikh Muhammad Hussein Yaqoub titled "The Qur’an Makes You."
