The Quran, however, claims to be a direct revelation from heaven, dictated to Muhammad. Allah rebuffs those who accused Muhammad of reciting "tales of the ancients" (25:4-6). And, Muslim scholars have spilled considerable ink trying to prove (unsuccessfully) that the Quran is wholly and culturally unique, and thus divinely revealed.
This 20 min video, which is a polemic, uncovers the original historical sources behind a number of Quranic stories. Rather than being a book dropped from heaven, the Quran underwent a historical process of literary formation indicative of its earthly origins.
Description: The first half the video traces the history of Old Testament stories in the Quran. Beginning at 9:41 the video turns to New Testament stories about Jesus, including the famous apocryphal tale in which He turns a clay bird into a real bird (13:39). This story is found in Quran 3:49 and 5:110. The historical parallels are given in full in the article, "Parallelism: Jesus Christ and Clay Birds."
