The term “human being” has no meaning inside of Islam. There is no such thing as humanity, only the duality of the believer and unbeliever. Look at the ethical statements found in the Hadith. A Muslim should not lie, cheat, kill or steal from other Muslims. But a Muslim may lie, deceive or kill an unbeliever if it advances Islam. There is no such thing as a universal statement of ethics in Islam. Muslims are to be treated one way and unbelievers another way. The closest Islam comes to a universal statement of ethics is that the entire world must submit to Islam. After Mohammed became a prophet, he never treated an unbeliever the same as a Muslim. Islam denies the truth of the Golden Rule.
By the way, this dualistic ethic is the basis for jihad. The ethical system sets up the unbeliever as less than human and therefore it is easy to kill, harm or deceive the unbeliever.
Now mind you, unbelievers have frequently failed at applying the Golden Rule, but we can be judged and condemned on its basis. We do fall short, but is our ideal.
