"If they refuse to accept Islam, demand from them the Jizya. If they agree to pay, accept it from them and hold off your hands. If they refuse to pay the tax, seek Allah's help and fight them. When you lay siege to a fort and the besieged appeal to you for protection in the name of Allah and His Prophet, do not accord to them the guarantee of Allah and His Prophet, but accord to them your own guarantee and the guarantee of your companions for it is a lesser sin that the security given by you or your companions be disregarded than that the security granted in the name of Allah and His Prophet be violated When you besiege a fort and the besieged want you to let them out in accordance with Allah's Command, do not let them come out in accordance with His Command, but do so at your (own) command, for you do not know whether or not you will be able to carry out Allah's behest with regard to them."
