Qisas, The Settlement
[2:178] O you who believe! Retaliation is prescribed for you in the mat- ter of the slain, the free for the free, and the slave for the slave, and the female for the female, but if any remission is made to any one by his (aggrieved) brother, then prosecution (for the bloodwit) should be made according to usage, and payment should be made to him in a good manner; this is an alleviation from your Lord and a mercy; so whoever exceeds the limit after this he shall have a painful chastisement.
[2:179] And there is life for you in (the law of) retaliation, O men of understanding, that you may guard yourselves.
[4:92] 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.
[5:44] Surely We revealed the Taurat in which was guidance and light; with it the prophets who submitted themselves (to Allah) judged (matters) for those who were Jews, and the masters of Divine knowledge and the doctors, because they were required to guard (part) of the Book of Allah, and they were witnesses thereof; therefore fear not the people and fear Me, and do not take a small price for My communications; and whoever did not judge by what Allah revealed, those are they that are the unbelievers.
[5:45] And We prescribed to them in it that life is for life, and eye for eye, and nose for nose, and ear for ear, and tooth for tooth, and (that there is) reprisal in wounds; but he who foregoes it, it shall be an expiation for him; and whoever did not judge by what Allah revealed, those are they that are the unjust.
[16:125] Call to the way of your Lord with wisdom and goodly exhortation, and have disputations with them in the best manner; surely your Lord best knows those who go astray from His path, and He knows best those who follow the right way.
[16:126] And if you take your turn, then retaliate with the like of that with which you were afflicted; but if you are patient, it will certainly be best for those who are patient.
[42:40] And the recompense of evil is punishment like it, but whoever forgives and amends, he shall have his reward from Allah; surely He does not love the unjust.
