ELICS ,
You ether don’t know the quran or you may choose to ignore the impact of its passages that incite violence.
Here are some for your easy reference:

“We have created, for hell, many genii (races) of men...and they are like brute beasts” (7.179)

“Verily, those who disbelieve our signs, we will surely cast them to be broiled in the hell-fire, so often as their skins shall be well burnt, We will give them new skins in exchange, so that they may taste the sharper torment” (4.56)

“Whosoever followeth any religion other than Islam, it shall not be accepted of him in this life, and in the next life he shall be of those who perish” (3.85)

“I will cast a dread into the hearts of the unbelievers” (8.12)

“Therefore cut off their heads, and strike off all the ends of the fingers. This shall they suffer because they have opposed Allah and His Prophet, and whosoever shall oppose Allah and His Prophet, verily Allah will be severe in punishing them” (8.13)

“moreover, as for the non-believers, I will punish them with grievous punishments in this world, and in the world is to come” (3.56)

“they shall suffer a grievous punishment” (3.77).

“They (believers) shall fight in the way of Allah and shall slay and be slain” (9:111).”

Now you may argue that the above quranic passages were written in a certain context and no longer should they be interpreted literally... maybe you are right... however... the main source of terror today, seeks its inspiration in these precise words!

My point is: why isn’t the world acknowledging this source, objectively and doing something effective to stop the bloody trend?!
