The results of this research show that both Ibn Sina and Mohammad Natsir chose a state system based on the Qur'an and hadith, so it is not surprising that Mohammad Natsir revealed that the main goal of the state is to realize Islamic teachings and laws, thus the state's goal is to happiness in this world and the hereafter. According to the two leaders, state leaders must pay attention to their obedience to Allah SWT. From the similarities and differences, the two figures have more similarities than differences, what differs from the two is that Ibn Sina focuses on economic revolution to realize the ideals of the state, while Mohammad Natsir does not specifically discuss the basic problems of the state.
