"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. This is supposing a general summons; for without that it is not lawful for a woman or slave to go forth to make war without the consent of the husband or master, as there is in this case no necessity for their assistance, since others suffice, and hence no reason exists for destroying the right of the husband or master on that account. If there be any fund in the public treasury, so long as the fund lasts any extraordinary exaction for the support of the warriors is abominable, because such exaction resembles a hire for that which is a service of God as much as prayer or fasting, and, hire being forbidden in these instances, so is it in that which resembles them. In this case, moreover, there is no occasion for any extraordinary exactions, since the funds of the public treasury are prepared to answer all emergencies of the Muslims, such as war, and so forth. If, however, there be no funds in the public treasury, in this case the Imam need not hesitate to levy contributions for the better support of the warriors, because in levying a contribution the greater evil (namely, the destruction of the person) is repelled, and the contribution is the smaller evil, and the imposition of a smaller evil to remedy a greater is of no consequence. A confirmation of this is found in what is related of the Prophet, that he took various articles of armour, and so forth, from Safwan and ‘Umar; in the same manner also he took property from married men, and bestowed it upon the unmarried, in order to encourage them and enable them to go forth to fight with cheerfulness; and he also used to take the horses from those who remained at home, and bestowed them upon those who went forth to fight on foot. 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.
