Because of this, we decreed for the Children of Israel that anyone who murders any person who had not committed murderSee? It says in the Koran not to kill people. It is against Islam.
or horrendous crimes, it shall be as if he murdered all the people.
And anyone who spares a life, it shall be as if he spared the lives of all the people.
Our messengers went to them with clear proofs and revelations,
but most of them, after all this, are still transgressing.
The just retribution for those who fight GOD and His messenger,
and commit horrendous crimes,
is to be killed, or crucified, or to have their hands and feet cut off on alternate sides, or to be banished from the land.
This is to humiliate them in this life, then they suffer a far worse retribution in the Hereafter.
So basically, the Koran teaches the proper punishment for anyone who "fights God and his messenger" is death. This which can easily be interpreted as, and is indeed often interpreted in the Jihad movement as, non-Muslims.
The last part of 5:32 says "see, we went and told them this, but most of them aren't listening." So they are fighting God and his Messenger, in effect. Death to them. Get it?
Note that Muslims are free to punish percieved non-believers in this life, whereas Christians and Jewish texts leave it up to God in the afterlife.
But see, they are merciful, too:
Exempted are those who repent before you overcome them. You should know that GOD is Forgiver, Most Merciful.
In other words, unless they become Muslims.
Islam is not compatible with Liberal Western thought. The leaders of the Jihad movement(s) not only know this, they proclaim it often in their speech and writings.
See these peaceful folks?
