Let's put it this way. Having growing up in a muslim country - I have been told many many times by folks who you would consider very moderate muslim and by the imam who leads thousand and thousand congregation members that according to Quran, to kill the infidels (all non muslim), a muslim still goes to nirvana/heaven.
The first 1/4 of Quran tells story of young Muhammad. The last 3/4 is about waging wars on the non believers.
If anyone could show that same violence encouragement in any religions, I am all ears. I am not a devout Christian by all mean - but there are 3 references to violence in the old testament. Christian also teaches if you believe in Him you will be saved whereas Muslim teaches nonbelievers shall be punished. Similar message - one is hope, the other one with stroke of fear.
Quran also mentions the Bible and Christian multiple time...
Commanding Christian beheading/execution?The unbelievers among the People of the Book
(the Book is the Bible) and the pagans shall burn for ever in the fire of Hell. They are the vilest of all creatures.
Quran 98:6
When you meet the unbelievers in the battlefield strike off their heads and, when you have laid them low, bind your captives firmly.
Quran 47:4Let not the unbelievers think that they will ever get away. They have not the power to do so. Muster against them all the men and cavalry at your command, so that you may strike terror into the enemy of God and your enemy...
Quran 8:59-60and so on... I am not an expert on the bible, but all those years they made me read Quran certainly have some of these imprinted in my mind. There countless of ex muslim or ex terrorist who speak so strongly against the muslim belief, but of course they are being ignored by the mainstream. Because to be politically correct, you must embrace all humanity even though some of them are brainwashed since birth. Call me bigot, but I know who my enemy are.Believers, make war on the infidels who dwell around you. Deal firmly with them. Know that God is with the righteous.
Quran 9:123
