Any teaching of Islam by Dr. Warner is well worth following, including, of course, this posting. Of special interest is his specific definitions from 12: 35 on, and even of greater importance, at 13: 25. The words “peace” and “slander” can lead to great loss when not understood. Barack Obama said at least once, “The future must not belong to those who slander the prophet of Islam.” What is “future?” Life, existence? Who are “those,” individuals, groups, nations? What is “slander?” As Dr. Warner tells us, slander is offensive speech to a Muslim even if true. I believe that anything that would show lack of belief in the teachings of Muhammad would be offensive.
