Infidels do not take the Divine books seriously considering it impossible for a humanbeing to be a messenger of Allah (SWT). They regard the message as magic, confused dreams, forgery, poetry etc. therefore they demanded a miracle from prophet Muhammed (PBH) as a proof of his Prophet hood. All messengers were human beings who ate food and died like ordinary human beings. Their communities did not believe and regretted after seeing the punishment but the messengers and their followers were saved. The Quran is a reminder yet they do not believe.
