"If a Muslim attack infidels without previously calling them to the faith, he is an offender, because this is forbidden; but yet if he do attack them before thus inviting them and slay them, and take their property, neither fine, expiation, nor atonement are due, because that which protects (namely, Islam) does not exist in them, nor are they under protection by place (namely the Daru ‘l-Islam, or Muslim territory), and the mere prohibition of the act is not sufficient to sanction the exaction either of fine or of atonement for property; in the same manner as the slaying of the women or infant children of infidels is forbidden, but if, notwithstanding, a person were to slay such, he is not liable to a fine. It is laudable to call to the faith a people to whom a call has already come, in order that they may have the more full and ample warning; but yet this is not incumbent, as it appears in the Traditions that the Prophet plundered and despoiled the tribe of al-Mustaliq by surprise, and he also agreed with Asamah to make a predatory attack upon Qubna at an early hour, and to set it on fire, and such attacks are not preceded by a call. (Qubna is a place in Syria: some assert it is the name of a tribe).

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.

Islam and infidelity (kufr) contradict one another. To establish the one means eradicating the other, the coming together of these contradictories being impossible. Therefore, Allah has commanded his Prophet to wage war (jihad) against the infidels, and be harsh with them. The glory is Islam consists in the humiliation and degradation of infidels and infidelity. He who honours the infidels, insults Islam. Honouring (the infidels) does not mean that they are accorded dignity, and made to sit in high places. It means allowing them to be in our company, to sit with them, and talk to them. They should be kept away like dogs. If there is some worldly purpose or work which depends upon them, and cannot be served without their help, they may be contacted while keeping in mind all the time that they are not worthy of respect. The best course according to Islam is that they should not be contacted even for worldly purposes. Allah has proclaimed in his Holy Word (Quran) that they are his and his Prophet’s enemies. And mixing with these enemies of Allah and his Prophet or showing affection for them, is one of the greatest crimes…
…The abolition of jizyah in Hindustan is a result of friendship which (Hindus) have acquired with the rulers of this land… What right have the rulers to stop exacting jizyah? Allah himself has commanded imposition of jizyah for their (infidels’) humiliation and degradation. What is required is their disgrace, and the prestige and power of Muslims. The slaughter of non-Muslims means gain for Islam… To consult them (the kafirs) and then act according to their advice means honouring the enemies (of Islam), which is strictly forbidden…
The prayer (=goodwill) of these enemies of Islam is false and fruitless. It should never be called for because it can only add to their numbers. If the infidels pray, they will surely seek the intercession of their idols, which is taking things too far… A wise man has said that unless you become a maniac (diwanah) you cannot attain Islam. The state of this mania means going beyond considerations of profit and loss. Whatever one gains in the service of Islam should suffice…

"It is not lawful to make war upon any people who have never before been called to the faith, without previously requiring them to embrace it, because the Prophet so instructed his commanders, directing them to call the infidels to the faith, and also because the people will hence perceive that they are attacked for the sake of religion, and not for the sake of taking their property, or making slaves of their children, and on this consideration it is possible that they may be induced to agree to the call, in order to save themselves from the troubles of war.

"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.

If you [Muslims] are under their [infidels] authority, fearing for yourselves, behave loyally to them, with your tongue, while harboring inner animosity for them. Allah has forbidden believers from being friendly or on intimate terms with the infidels in place of believers except when infidels are above them [in authority]. In such a scenario, let them act friendly towards them.

Neither I had any knowledge of these attacks nor I consider the killing of innocent women, children, and other humans as an appreciable act. Islam strictly forbids causing harm to innocent women, children, and other people. Such a practice is forbidden ever in the course of a battle. … It is the United States, which is perpetrating every maltreatment on women, children and common people of other faiths, particularly the followers of Islam.

The Islamic principles of denigrating the non-Muslims, of aggression and violence against them - principles that perpetually incite to riot and rapine - have boomeranged. However brave face the fundamentalists may try to put up, the victims of Islam today are by and large Muslims themselves. The Prophet must have known that violence begets violence and repeatedly exhorted Muslims not to kill one another after his death. He also had a premonition that violence of Islam against non-Muslims will be met with a backlash. There is a hadis in Sahih Muslim which says that once the Rasul opined that Islam which began in poverty in Medina would one day return to Medina in poverty. 'Just as a snake crawls back and coils itself into a small hole, so will Islam be hunted out from everywhere and return to be confined to Mecca and Medina.' The increasing power of the non-Muslim West and the disenchantment of Muslim dissidents point towards that possibility, howsoever remote.

Islam, the religion of tolerance, holds the human soul in high esteem, and considers the attack against innocent human beings a grave sin; this is backed by the Qur'anic verse that reads: "Who so ever kills a human being for other than manslaughter or corruption in the earth, it shall be as if he has killed all mankind, and who so ever saves the life of one, it shall be as if he had saved the life of all mankind," (Al-Ma'idah:32).... I categorically go against a committed Muslim's embarking on such attacks.

The killing of infidels by any method including martyrdom (suicide) operations has been sanctified by many scholars even if it means killing innocent Muslims...The shedding of Muslim blood...is allowed in order to avoid the greater evil of disrupting jihad.

There's only one faith, for example, that kills you or wants to kill you if you draw a bad cartoon of the prophet. There's only one faith that kills you or wants to kill you if you renounce the faith... obviously, most Muslim people are not terrorists. But ask most Muslim people in the world, if you insult the prophet, do you have what's coming to you? It's more than just a fringe element.

It is our constant object and sincere intention, that those worthless and stiff-necked infidels, who have turned aside their heads from obedience to the true-believers, and openly raised the standards of infidelity, should be chastised by the hands of the faithful, or made either to acknowledge the true religion or to pay tribute, particularly at this time, when owing to the imbecility of the princes of Hind, that insolent race having conceived the futile opinion, that the true believers are become weak, mean and contemptible; and not satisfied even with this, but preparing for war, have over-run and laid waste the territories of the Moslems, and extended the hand of violence and injustice on the property and honour of the faithful.
...Whosoever shall refuse to give ear to these words, shall contravene their promulgation, shall be considered as destitute of [every particle of] honour [or zeal], as a stranger to [or no participator in] the bliss derived from [a steady]faith, and as deserving to be banished from the presence of God, to be excluded from the circle of the faithful and to be accounted as one of the accursed infidels.
