Shaykh Abd al-Aziz ibn Baz advised non-Muslims seeking to understand Islam to begin by turning directly to its foundational sources with a sincere heart. The most crucial step is to ask Allah (God) Himself for guidance to the truth.

First, one should engage with the Qur'an. It is recommended to read a reliable translation of the meanings of the Qur'an to understand its core message concerning the oneness of God (Tawhid), the purpose of creation, the stories of the prophets, and the reality of the Hereafter. The Qur'an is the literal word of God, and its message is the ultimate foundation of the faith.

Second, one should study the life and character of the Prophet Muhammad (peace and blessings be upon him) as conveyed in the authentic Sunnah (his sayings, actions, and approvals). His life is the practical embodiment of the Qur'anic teachings, and understanding his example is essential to understanding Islam as a complete way of life. Authentic biographies (Seerah) and collections of his traditions (hadith) are the key resources for this.

Shaykh Ibn Baz would also stress the importance of distinguishing between the pure teachings of Islam found in these sources and the cultural practices or innovations of some Muslims, which may not be representative of the faith. A non-Muslim should be careful to take knowledge from trustworthy, knowledgeable Muslims who adhere to the Qur'an and Sunnah, and avoid sources that promote misinterpretations or deviant ideologies. Pondering the signs of God in the universe is also encouraged, as this is a method the Qur'an itself uses to lead a person to recognize their Creator.
