A common allegation, which was raised by polytheists of Makka, responded by Quran is again raised by Christian brothers:
"Prophet Muhammad (pbuh) was under the influence of Satan, who dictated Quran."
Let's analyze this claim, allegation logically. As it is said the "the taste of pudding is in eating".
Jesus Christ said:
Matthew 7:16-18
"You will know them by their fruits. Grapes are not gathered from thorn bushes nor figs from thistles, are they? "So every good tree bears good fruit, but the bad tree bears bad fruit. "A good tree cannot produce bad fruit, nor can a bad tree produce good fruit.…
Matthew 12:33
"Make a tree good and its fruit will be good, or make a tree bad and its fruit will be bad, for a tree is recognized by its fruit.
Matthew 12:35
A good man brings good things out of the good stored up in him, and an evil man brings evil things out of the evil stored up in him.
If Quran was from Satan, the teachings should reflect the same, there should be praises for Satan and appreciation not curses. All messengers of God from Noah, Abraham, Jacob, Moses, to Jesus Christ preached : Obedience and worship of One God. Prophet Muhammad (pbuh) did not preach worship of 2 or 3 gods or Gods. His message is the same monotheistic: Obedience and surrender to the will of God
[one word for it in Arabic word ISLAM] hence it is rightly claimed that the religion of all TRUE messengers of God is same. God is "All Knowing" how can a true God change His basic message? Change was only in law. Shari'a according to the people and time. Now it stands resolved for ever for humanity.
The Quran makes it clear that God is the author of the Quran…not Satan:
26:210-212:
The devils did not bring it (the Quran) down. It is not meet for them, nor is it in their power, Lo! verily they are banished from the hearing.
55:1-2:
The Most Beneficent (Allah)! Has taught (you mankind) the Qur’an (by His Mercy).
The Quran opposes Satan as a staunch enemy…
2:168 :
O mankind! Eat of that which is lawful and wholesome in the earth, and follow not the footsteps of the devil. Lo! he is an open enemy for you.
7:200 :
And if a slander from the devil wound thee, then seek refuge in Allah. Lo! He is Hearer, Knower.
16:98:
“Whenever you read the Qur’an seek refuge with Allah from Satan, the accursed”
36:60:
Did I not charge you, O ye sons of Adam, that ye worship not the devil – Lo! he is your open foe! -
Now anyone who studies the Quran and knows about its scientific miracles , prophecies , falsification tests etc. can do nothing but conclude that it came from a supernatural source, the God.
If Jesus Christ heard such allegation he would have rebuked it just like how he rebuked the Pharisees who accused him of casting out Satan with the power of Satan…
Mark 3:22-26:
"And the teachers of the law who came down from Jerusalem said, “He is possessed by Beelzebub[c]! By the prince of demons he is driving out demons.” So Jesus called them and spoke to them in parables: “How can Satan drive out Satan? If a kingdom is divided against itself, that kingdom cannot stand. If a house is divided against itself, that house cannot stand. And if Satan opposes himself and is divided, he cannot stand; his end has come."
The story is repeated in the gospel of Matthew…
Matthew 12:24-26: 24
But when the Pharisees heard this, they said, “It is only by Beelzebub,[d] the prince of demons, that this fellow drives out demons.” 25Jesus knew their thoughts and said to them, “Every kingdom divided against itself will be ruined, and every city or household divided against itself will not stand. 26If Satan drives out Satan, he is divided against himself. How then can his kingdom stand?
Devil tempted Adam, Eve got them out of gardens of bliss , tempted Jesus Christ but was rebuked:
“Away from me, Satan! For it is written: ‘Worship the Lord your God, and serve him only.”[Matthew 4:10]
The disappointed Satan later got Paul in vision [as did David Koresh and Jim Jones] and possessed him. It is not allegation its proved from Bible:
Paul under Satanic influence:
According to 2 Corinthians 12:6-9, Paul, in the Bible says:
“But I refrain, so no one will think more of me than is warranted by what I do or say, or because of these surpassingly great revelations. Therefore, in order to keep me from becoming conceited, I was given a thorn in my flesh, a messenger of Satan, to torment me. ” -2 Corinthians 12:6-7
”According to ‘Saint’ Paul, God sent a Messenger of Satan to teach him the reality of grace.
If it is a Messenger from God,why then, does Paul call it a Messenger of Satan?
Since it is from God, shouldn’t it be a Messenger of God? Since Paul calls Messengers sent by Christ to teach him grace, Satan, and since Paul is tormented and Christ is unwilling to remove the ‘Messenger of Satan’,
then we must conclude that Paul was a man possessed by some demon. His
teachings contradict Jesus Christ, so it suffice to prove the Satanic influence:
"A good man brings good things out of the good
stored up in him, and an evil man brings evil things out of the evil
stored up in him."(Matthew 12:35)
The dubious VISION of Paul and conversion story is exposed due to conflicting account at Act, chapters 9,22 & 26. Then the influence of Messenger of Satan, resulted in such doctrines which Jesus Chrsit never preached, he said:
Matthew 7:21-26:
“Not everyone who says to me, ‘Master, Master ‘will enter into the Kingdom of Heaven; but he who does the will of my Father who is in heaven. Many will tell me in that day, ‘Master, master didn’t we prophesy in your name, in your name cast out demons, and in your name do many mighty works?’ Then I will tell them, ‘I never knew you. Depart from me, you who work iniquity.‘ “Everyone therefore who hears these words of mine, and does them, I will liken him to a wise man, who built his house on a rock. The rain came down, the floods came, and the winds blew, and beat on that house; and it didn’t fall, for it was founded on the rock. Everyone who hears these words of mine, and doesn’t do them will be like a foolish man, who built his house on the sand.”
“For this people’s heart has become calloused; they hardly hear with their ears, and they have closed their eyes. Otherwise they might see with their eyes, hear with their ears, understand with their hearts and turn, and I would heal them.” [Matthew 13:15]
“But everyone who hears these words of mine and does not put them into practice is like a foolish man who built his house on sand” [Matthew 7:26]
“And He said to them, “Rightly did Isaiah prophesy of you hypocrites, as it is written: ‘THIS PEOPLE HONORS ME WITH THEIR LIPS, BUT THEIR HEART IS FAR AWAY FROM ME. ‘And in vain they pay reverence [Greek sebomai sebomai, revere, worship, adore] to me as they teach doctrines of commandments of the sons of men.’ “Neglecting the commandment of God, you hold to the tradition of men.” [Mark 7:6-10]
These arguments should satisfy our Christian brothers and create awareness in their hearts to follow true teachings of Jesus Christ not of the Paul.
"But nay! I swear by all that ye see . And all that ye see not. That it is indeed the speech of an illustrious messenger. It is not poet's speech - little is it that ye believe! Nor diviner's speech - little is it that ye remember! It [Quran] is a revelation from the Lord of the Worlds. And if he had invented false sayings concerning Us, We assuredly had taken him by the right hand. And then severed his life-artery, And not one of you could have held Us off from him. And lo! it is a warrant unto those who ward off (evil). And lo! We know that some among you will deny (it). And lo! it is indeed an anguish for the disbelievers. And lo! it is absolute truth. So glorify the name of thy Tremendous Lord. (Quran; 69:38-52)
