“Operation Iraqi Freedom, Operation Enduring Freedom/Afghanistan” these are some of the words which the kafirs used to deceive people while fighting against the Muslims. in the initial stage to conquer Iraq they were fighting to stop weapons of mass destruction. But later the world came to know they (the US, Isreal and its allies) are the ones who are using them. Depleted uranium is being used in their ammunition in Palestine, Iraq, Afganistan and currently now on libya. Below pictures shows the Birth defects in Iraq as a result of these weapons.
Allah (SW) says “They (the disbelievers, the Jews and the Christians) want to extinguish Allah’s Light (with which Muhammad SAW has been sent – Islamic Monotheism) with their mouths, but Allah will not allow except that His Light should be perfected even though the Kafirun (disbelievers) hate (it). ” At-Tawba 9:32.
So from the verse we should understand that the kafirs are not fighting to get oil or to get the lands, they are fighting because we are Muslims. this is a war against Islam.
