Hi Hindustani. Ofcourse Allah ordered in Quran to kill all idol worshippers but this order was given to Muhammad SAW and his companion when they were in a battle of war. The people with whom the war was going on were Idol Worshippers but the reason behind this war was not religion but because they had looted the properties of Muslims of that time and had killed their parents and relatives just because they had accepted Islam. In the same chapter Allah orders Muhammed SAW and his companions that "you shall fight against them but if they don't want to fight then you should not harm them and rather take them to a safe place and leave them."
Don't you know that according to Geeta in a batter of war of Pandav and Kaurav even Sri Krishna asked Arjun to not get emotional and rather stand still and kill the opponents even if he is his relative. Then does this mean that Sri Krishna had a terrorism mind? NO. This is a rule of war. you have to kill your opponents.
Allah says in Quran that "If anybody kills an innocent person then he will be punished as if he as killed the whole mankind and if anybody saves the life of innocent then he will get a reward as if he has saved the whole mankind."
Now You are talking about common sense. Use your common sense and think that Mughal Emperors have ruled India for more than 300 years and had they killed all idol worhshippers then only few years would have been enough for them to convert India to a 100% Muslim populated Country. Grow up
