Instead of telling Muslims what is "wrong" in their Quran, it would be easier to bring a "Duplicate Quran", since you know the source of it. And it is very easy. Just copy stories of Bible, divide it into pieces and just distribute it here and there.<quoted text>
There is no point to make that challenge if a Muslim is unable to recognize the flaws on its own book, the Quran.
More or less this is the position of Muslims: Like a mum would say his son is perfect, good ect, while in reality any son has its strong and weak points, but for its mother he's perfect.
If a group of people present to the mother a child that is better than her own, she will keep saying her son is better, and point out the flaws of the other child.
It's just a waste of time. Moreover how long have you been here? People have showed you all the mistakes in Quran. Sometimes you gave good answers, other time that answers were not so convincing. In other cases you escaped from the questions, or just said Allah knows best when you were speechless in front of the evident mistakes.
What about the birth of Jesus that was taken from Infacy Gospels?
Allah confusing Gideon's story with Saul's one, and many others?
No Chronology, No theme, no grammar, anything would pass.
Why not conjure a single four short verse chapter like Chapter 112, that blows away Trinity, Idol Worship, False gods worship, Son of God and Father of God and every other cobwebs that humans have ever designed to worship any one else, except the True Lord of Universe.
It should be a "piece of cake" for some one like you.
I did not hear any thing from you so far, go have a hand at it. Write something in English first, then get it Translated in Arabic thru "Google Translator"!!
Vow, that would be fine!!
