“Careful, detailed, well-reasoned. . . . [A] brave book.” —FrontPage Magazine

“This will send shockwaves through Islamic communities.” —The Blaze

“In an impeccably researched book, Spencer shows that all our Arabic sources for the life of Muhammad are very late, tendentious, and unsupported by any archaeological or epigraphic evidence, while the non-Islamic sources are scant and ambiguous. Thanks to this book, skepticism regarding what we can know about Muhammad must now and forever be taken seriously.” —Ibn Warraq, editor of What the Koran Really Says

“A surprising and eye-opening new book . . . Quite a convincing job.” —PJ Media

“Robert Spencer has displayed brilliant scholarship and fierce courage in his previous books. In this one he perseveres and confronts with deep erudition the most topical problem of our century.” —Bat Ye’or, author of The Decline of Eastern Christianity under Islam

“A super detective service for the West . . . Spencer leaves few rocks unturned in his search for the truth about Islam and Muhammad.” —Capitalism Magazine

“[Spencer] has engaged in concerted detective work of a scholarly nature. His book is no polemic. It is a serious quest for facts. . . . Well-written and moves right along.” —--This text refers to an alternate kindle_edition edition.
