(Before It's News)
Many Muslim speakers and apologists assert that the Qur’an contains scientific miracles, and that Muhammad made claims about science that were not verified until centuries after his death. However, when we actually examine the Muslim sources (the Qur’an, the Hadith, the Sira, and the Tafsir), we find that Muhammad was wrong about almost everything he said concerning science. The only scientific statements Muhammad got right would have been known by virtually anyone in seventh-century Arabia. Hence, the “argument from scientific accuracy” fails rather miserably.
