What is the response of the pure Sharia to the assertion of the relativity of ethics?

The notion of ethical relativism is a destructive philosophy stemming from the relativism of truth itself. Sheikh al-Islam Ibn Taymiyyah held that no sane person would espouse this view. Ibn Hazm refuted this notion by asserting that something does not become true by the belief of one who considers it true, nor does it become false by the belief of one who considers it false. Rather, something is true by virtue of its existence and stability. Dr. Ahmad Abd al-Rahman explained that relativistic philosophy is the intellectual bedrock for all movements hostile to the principle of "Islamic permanence" in creed, law, and ethics. It claims that truths, values, and principles change with the alteration of time and place. The former Grand Imam of Al-Azhar, Dr. Abd al-Halim Mahmud, stated that this philosophy is a Jewish doctrine that works to sow doubt in values, ideals, beliefs, and ethics. Dr. Mubarak Baqanah believes that ethical relativism means the absence of absolute ethics, thus allowing individuals to adopt the ethics they desire. Denying absolute ethics is a denial of faith-based values and renders society fragile, susceptible to disintegration and dissolution.
