Yes, reading the Old Testament, the New Testament and the Quran and comparing them is really instructive. However Quran is just one of the two primary sources (the messages received by Muhammad), you&#x27;d have to read Sunnah for the deeds of Muhammad during which he received the messages (the second primary source). It&#x27;s only there that you&#x27;d find the beheadings and stonings by Muhammad. Just like &quot;the New testament&quot; isn&#x27;t just one of the gospels, but the four gospels and all the other books, including the Apocalypse of John and all the epistles.<p>Sunnah are also searchable online.
