It is no objection to shooting arrows or other missiles against the infidels that there may chance to be among them a Muslim in the way either of bon… - Burhan al-Din al-Murghinani

If the Imam make peace with the aliens in return for property, there is no scruple; because since peace may be lawfully made without any such gratification it is also lawful in return for a gratification. This, however, is only where the Muslims stand in need of the property thus to be acquired; for if they be not in necessity, making peace for property is not lawful, since peace is a desertion of war both in appearance and in effect. It is to be observed that if the Imam receive this property by sending a messenger and making peace without the Muslim troops entering the enemy's territory, the object of disbursement of it is the same as that of jizyah or capitation-tax; that is, it is to be expended upon the warriors and not upon the poor. If, however, the property be taken after the Muslims have invaded the enemy in this case it is as plunder, one-fifth going to the Imam and the remainder to be divided among the troops, as the property has in fact been taken by force in this instance. It is incumbent on the Imam to keep peace with apostates, and not to make war upon them, in order that they may have time to consider their situation, since it is to be hoped that they may again return to the faith. It is, therefore, lawful to delay fighting with them in a hope that they may again embrace Islam; but it is not lawful to take property from them. If, however, the Imam should take property from them, it is not incumbent upon him to return it, as such property is not in protection. If infidels harass the Muslims, and offer them peace in return for property, the Imam must not accede thereto as this would be a degradation of the Muslim honour, and disgrace would be attached to all the parties concerned in it; this, therefore, is not lawful except where destruction is to be apprehended, in which case the purchasing a peace with property is lawful, because it is a duty to repel destruction in every possible mode.

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.

"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.
