Some Christians say the Quran is from Satan
A more base claim they make is that the Quran is from the Devil. Christians who tend to make this claim are the extremely lay but tend to be the very devout Christians. These Christians make such base claims out of their own lack of knowledge and the fact the their extreme devotion to their faith renders them with a very ‘black and white’ perspective; they generally view things that oppose their faith as evil and devil-inspired’.
The Christians who do make such a claim do expose their own ignorance of Islam and Christianity. This is because whenever a Muslim intends to read the Quran he/she will seek refuge from the Devil and if we look into the Quran we realise that the Quran in chapter 2 and verse 168 teaches us that the Devil is an enemy to mankind: 2:168. O ye people! Eat of what is on earth, Lawful and good; and do not follow the footsteps of the evil one, for he is to you an avowed enemy. (1)
So the obvious conclusion we draw from this knowledge is that the Quran is not from the Devil as the devil would not teach such teachings. The Christian may continue to make this claim despite this information, if this is the case then the humiliation and exposing of a lack of knowledge on the part of the Christian who makes this claim continues as the Muslim can easily point to the misery that alcohol causes mankind (including the misery that is Fetal Alcohol Syndrome). Christianity allows the drinking of alcohol while the Quran forbids the consummation of alcohol. Fetal Alcohol Syndrome (FAS) occurs "when a woman drinks alcohol during pregnancy, she risks giving birth to a child who will pay the price — in mental and physical deficiencies — for his or her entire life" (2). Some of the symptoms of Fetal Alcohol Syndrome affecting the child are delayed development, organ dysfunction, failure to thrive, facial abnormalities and can lead to mental helath problems and troubles with the law in later life (2).
Why is all this relevant to the Quran? Well, the Christian claims that the Quran is from Satan yet the Quran has saved millions of children from this horrendous disease while the Bible has not. So this is further humiliation and refutation poured upon the mindless claim of the missionaries.
The question to ask them is; how did the Quran (which they say is from Satan) save millions of children from Fetal Alcohol Syndrome (and from other alcohol related diseases) while the Bible (which they believe to be fully from God) allowed the drinking of alcohol and allowed Fetal Alcohol Syndrome to affect millions of children?
Surely God gives us wholesome teachings (ie forbidding alcohol) and Satan teaches us impure teachings (ie drinking alcohol). This would leave the Christian speechless and Insha’Allah (God Willing) the honest Christian will realise that this is a sign that the Quran is from God.
This argument (that Satan would not teach/promote teachings which are good or against Satan) is supported by the Bible in Mark 3:23 where the Christian is taught that Satan does not drive himself out (3). Thus the Christian would accept this Muslim response and recognise that the Quran is not from Satan.
It is also important to note that you wil always come across Christians who will not relent and will continue in their unscholarly ways despite all the logic and fine refutation you point them to.
