Can you please give me one example where you read that Mohammad(PBUH)taught violence?? If violence wud have been taught Islam wudn't have become the largest religion of world? If a mercedes benz car is driven by a novice driver & accidents occurs, wud you blame driver or car? But natural, the driver. So problem is with the people 'so called muslims' who have become guardians of Islams but there knowledge is very shallow.
