This research concludes, Ibnu Rusyd proved the existence of God by proposing no propositions, namely the Dalil al Inayah (providence of God), Dalil al-Ikhtira (the proposition of creation), and Dalil al Harakah (the proposition of motion). We witness that everything that has no sense, like for example, natural body, towards the end. The analysis obtained in proving the existence of God by Ibnu Rusyd is acknowledging the existence of God. Their intellect and revelation become the source of knowledge and tools to achieve truth, especially in proving the existence of God.
