Are all the fundamentals of the religion mentioned in the Noble Qur’an, and are they detailed and clarified by the Prophetic Sunnah?

The foundations of religion are clearly explained in the Quran and Sunnah, so everything people need to know about these issues has been clarified by Allah and His Messenger with a comprehensive explanation. As for the second part, which is the proofs for these issues, contrary to the assumption of some theologians and philosophers that the evidence of the Sharia is limited to truthful reports, Allah has clarified sufficient rational proofs for knowing them. The Quran has presented the essence of this in the best possible way.
