If you fail to respond to all these conditions, then prepare for fight with the Islamic Nation. The Nation of Monotheism, that puts complete trust on Allah and fears none other than Him. The Nation which is addressed by its Quran with the words: 'Do you fear them? Allah has more right that you should fear Him if you are believers. Fight against them so that Allah will punish them by your hands and disgrace them and give you victory over them and heal the breasts of believing people. And remove the anger of their [Muslims'] hearts'.
