text: Don’t worry about your english. Its just fine.\n\n1. Allah did create us into tribes and communities, so that we may know each other, recognise each other. Allah never distributed us on the religious lines as your question says. Religion has always been One. And that is - that worship Allah alone. Don’t associate partners unto Him. That’s been the message of all the messengers of God. \n\n2. Islam does allow fighting, but only against those who create trouble on earth. Sometime force has to be applied to establish peace. That’s what our police and military does. At the same, Qur’aan also says that if you a kill an innocent person, then its like killing whole of humanity.\n\n3. Allah does have power over everything. He is Supreme. There in none like Him. If Allah had wanted, he would have guided everyone on the Straight Path. But this is life is a test. He has shown us path through His messengers. Its up to us make or mar our lives.  \n\nWish you the very best.\nTake care
