The Sacred month for the sacred month and all sacred things are (under the law of) retaliation; whoever then acts aggressively against you, inflict injury on him according to the injury he has inflicted on you and be careful (of your duty) to Allah and know that Allah is with those who guard (against evil).

And it does not behoove a believer to kill a believer except by mistake, and whoever kills a believer by mistake, he should free a believing slave, and blood-money should be paid to his people unless they remit it as alms; but if he be from a tribe hostile to you and he is a believer, the freeing of a believing slave (suffices), and if he is from a tribe between whom and you there is a convenant, the blood-money should be paid to his people along with the freeing of a believing slave; but he who cannot find (a slave) should fast for two months successively: a penance from Allah, and Allah is Knowing, Wise.

O you who believe! do not violate the signs appointed by Allah nor the sacred month, nor (interfere with) the offerings, nor the sacrificial animals with garlands, nor those going to the sacred house seeking the grace and pleasure of their Lord; and when you are free from the obligations of the pilgrimage, then hunt, and let not hatred of a people-- because they hindered you from the Sacred Masjid-- incite you to exceed the limits, and help one another in goodness and piety, and do not help one another in sin and aggression; and be careful of (your duty to) Allah; surely Allah is severe in requiting (evil).
