"If the infidels, upon receiving the call, neither consent to it nor agree to pay capitation tax, it is then incumbent on the Muslims to call upon God for assistance, and to make war upon them, because God is the assistant of those who serve Him, and the destroyer of His enemies, the infidels, and it is necessary to implore His aid upon every occasion; the Prophet, moreover, commands us so to do. And having so done, the Muslims must then with God’s assistance attack the infidels with all manner of warlike engines (as the Prophet did by the people of Ta’if), and must also set fire to their habitations (in the same manner as the Prophet fired Baweera), and must inundate them with water and tear up their plantations and tread down their grain because by these means they will become weakened, and their resolution will fail and their force be broken; these means are, therefore, all sanctified by the law."
