The study of Islamic heritage by predecessors of the Ummah regarding moral philosophy reflects the views and thoughts of Muslim philosophers who have elucidated the nature and essence of ethics and discussed its fundamental principles and theoretical foundations. In the introduction of these intellectuals, two prominent Islamic philosophers, Imam Abu Hamid Muhammad Ghazali and Abu Ali Ahmad ibn Muhammad Miskawayh, stand out among others. The perspective of these Muslim philosophers on the concept, subject, and goals of the science of ethics, as well as the originality of their theories concerning their relative dependence on the ethical theories of Greek philosophers, is a matter that requires an analytical-descriptive investigation. The present findings indicate that the ethical theory of these two great thinkers generally aims at objectives such as the growth and elevation of moral conscience, purification of the soul, purification of the heart and inner self, strengthening the relationship between the self and the Almighty Creator, moral refinement and optimization, organizing and rectifying human conduct and behavior, achieving balance among the dimensions of human existence, strengthening fraternal bonds, cooperation and benevolence within society, and institutionalizing goodness and virtue, wisdom, courage, chastity, and justice among society and humanity at large by adhering to Islamic ethical standards.
