Well, you have to be careful about "promoting both the Bible and the Quran together" as them being both something to refer to for the truth. There can only be one truth and that truth is the Bible. The Muslims discount Jesus Christ and only recognize about the first 5 books of the God's word, the Bible, so be very careful about even putting the Quran anywhere near the truthfulness of the Bible, God's word.
Secondly, about magic.... Here is some accurate truth about magic:
Magic’s Influence Throughout History
From the dawn of history, man has been intrigued and manipulated by the mystery of magic. The word “magic” is derived from the name “magi,” an ancient Persian priestly caste that specialized in cultic activities. In its most basic sense, magic is an effort to control or coerce natural or supernatural forces to do man’s bidding. Egypt of the 18th century B.C.E. employed magic-practicing priests. Magic also played a prominent part in the religion of the ancient Chaldeans of Babylonia in the eighth century B.C.E. (Genesis 41:8, 24; Isaiah 47:12-14; Daniel 2:27; 4:7) This influence prevailed among the ancient Greeks and Romans down through the Middle Ages and right into our 20th century.
Three Forms of Magic
Mystical magic is “an expression of the occult.” It claims that “events or processes that contradict common-sense knowledge or scientific knowledge” are “true or valid.” Further explained, “mystical magic is the handmaid of sorcery, . . . witchcraft, alchemy, and, under certain conditions, religion (false religion; AKA: Babylon the Great Harlot which encompasses all of false religions).”
With exploitative magic, “practitioners manipulate or exploit the onlookers’ perception of reality for their own aggrandizement.” They know they are deceiving the public, but “they encourage those who witness the magic to believe otherwise—to believe that, as magicians, they have supernatural powers or special connections with beings who do.”
Entertainment magic aims to inspire wonderment through intriguing deception. It falls into five basic and overlapping methods: “stage magic, close up, sleight of hand, illusion, and mentalism.”
What about mystical magic. Mystical magic is invoked in various ways. For example, Satanists exist who practice both “black” and “white” magic. “Black” magic involves the casting of spells, special curses, and the evil eye to bring harm to one’s enemies. “White” magic, on the other hand, is intended to produce good results by breaking spells and canceling curses. Yet, both are expressions of the occult or the mystical. On occasion mystical magic is even called upon to attempt to get a good harvest or to win an athletic contest. Nevertheless, concerning this type of spiritistic magic, the Bible speaks frankly: “You must not look for omens, and you must not practice magic.” (Leviticus 19:26; Deuteronomy 18:9-14; Acts 19:18, 19)
Where does the danger lurk in exploitative magic? Palm readers, fortune-tellers, and faith healers, to mention a few, apply exploitative magic to advance their own interests. Are they not living a lie by their profession? God’s Word says: “You must not deceive, and you must not deal falsely anyone with his associate.” (Leviticus 19:11)
Leviticus 19:26 tells us:
"YOU must eat nothing along with blood. YOU must not look for omens, and YOU must not practice magic".
Deuteronomy 18:10-14 tells us:
There should not be found in you anyone who makes his son or his daughter pass through the fire, anyone who employs divination, a practicer of magic or anyone who looks for omens or a sorcerer, or one who binds others with a spell or anyone who consults a spirit medium or a professional foreteller of events or anyone who inquires of the dead. For everybody doing these things is something detestable to Jehovah, and on account of these detestable things Jehovah your God is driving them away from before you. You should prove yourself faultless with Jehovah your God.
Acts 19: 18 - 19 tells us:
And many of those who had become believers would come and confess and report their practices openly. Indeed, quite a number of those who practiced magical arts brought their books together and burned them up before everybody. And they calculated together the prices of them and found them worth fifty thousand pieces of silver.
The master in the art of deception and illusion is none other than Satan the Devil. He has been practicing this art ever since his first performance before a human in the garden of Eden. (Genesis 3:1-19)
What Christian would want to be like him? Instead, Christians are counseled to “become imitators of God” and to “subject [themselves] . . . to God; but oppose the Devil.” (Ephesians 5:1; James 4:7)
