According to Zakir Naik (and many other Muslim apologists), Isaiah29:12 contains a prophecy about Muhammad. The verse states: “Then the book will be given to the one who is illiterate, saying, ‘Please read this.’ And he will say, ‘I cannot read.'” Zakir Naik claims that since this is exactly what happened to Muhammad, the Bible contains a clear prophecy about Muhammad. But what happens when we read the verse in context and realize that Isaiah29:12 is about a man who stubbornly rejects God’s revelations and refuses to obey God? If this is about Muhammad, then Muhammad is a rebel against God!
