""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)."
