Praise be to Allaah.
The sources of Islam on which all beliefs, principles and rulings are based are represented by the two Revelations: the Qur’aan and Sunnah. This is what is implied by Islam being a divinely-revealed religion: its pillars are based on infallible texts that were sent down from heaven, which are represented in the verses of the Holy Qur’aan and the texts of the saheeh Prophetic Sunnah.
