ما هي الآيات القرآنية التي تثبت أن الإسلام رباني المصدر؟

There is no difference in argumentation and authoritative force between the Qur'an and the Sunnah, for both are divine revelations. Islam is a divine religion originating from God, and He has guaranteed its preservation, which is sufficient proof of its divine origin. The Qur'anic texts affirm that Islam is God's complete and preserved religion, and that the Prophet conveyed what was revealed to him, not speaking out of his own desire. Similarly, the Sunnah affirms that the Prophet received his knowledge from God, and that he did not claim anything from himself, which indicates that Islam is not a human composition, but rather a divine revelation.
