I have noticed here so many times that the average Christian does not know what is actually in the Bible and this leads them to say things that actually go against the Bible. This is why the Quran is Vital in understanding what God wants from us all.
Today many Islamic countries and Muslims all over have taken up many ways of the Jews of the Old testament ways that many Christians condemn as being wrong and yet the Quran does not condone these activities but in-fact it is the Bible itself that condones these things.
There is no prescription of stoning in the Quran but there is in the Bible.
It seems each time someone accuses Islam of something evil I find it in the Bible and not in the Quran so reading the Quran is Vital to understanding and better yet vital to understanding that Most Christians have no idea what is in the Bible.
Stephen was STONED to DEATH by Jews and this was after Jesus prevented the stoning of the adulterer so obviously the NT does not show this act being stopped because of Jesus
