""It is not incumbent upon infants to make war, as they are objects of compassion; neither is it incumbent upon slaves or women, as the rights of the master, or of the husband, have precedence; nor is it so upon the blind, the maimed, or the decrepid, as such are incapable. If, however, the infidels make an attack upon a city or territory, in this case the repulsion of them is incumbent upon all Muslims, insomuch that a wife may go forth without consent of her husband, and a slave without the leave of his master, because war then becomes a positive injunction; and possession, either by bondage or by marriage, cannot come in competition with a positive injunction, as in prayer (for instance) or fasting.... When the Muslims enter the enemy’s country and besiege the cities or strongholds of the infidels, it is necessary to invite them to embrace the faith, because Ibn ‘Abbas relates of the Prophet that he never destroyed any without previously inviting them to embrace the faith. If, therefore, they embrace the faith, it is unnecessary to war with them, because that which was the design of the war is then obtained without war. The Prophet, moreover, has said we are directed to make war upon men only until such time as they shall confess, ‘There is no God but one God. But when they repeat this creed, their persons and properties are in protection (aman). If they do accept the call to the faith, they must then be called upon to pay jizyah, or capitation tax, because the Prophet directed the commanders of his armies so to do, and also because by submitting to this tax war is forbidden and terminated upon the authority of the Qur’an. (This call to pay capitation tax, however, respects only those from whom the capitation tax is acceptable, or, as to apostates and the idolaters of Arabia, to call upon them to pay the tax is useless, since nothing is accepted from them but embracing the faith, as it is thus commanded in the Qur’an). If those who are called upon to pay capitation tax consent to do so, they then become entitled to the same protection and subject to the same rules as Muslims because ‘Ali had declared infidels agree to a capitation tax only in order to render their blood the same as Muslims’ blood, and their property the same as Muslims’ property."
