The word(s) "equality" appears 4 time(s) in 4 verse(s) in Quran in Mohsin Khan translation.

(1) O you who believe! Al-Qisas (the Law of equality in punishment) is prescribed for you in case of murder: the free for the free, the slave for the slave, and the female for the female. But if the killer is forgiven by the brother (or the relatives, etc.) of the killed against blood-money, then adhering to it with fairness and payment of the blood-money to the heir should be made in fairness. This is an alleviation and a mercy from your Lord. So after this whoever transgresses the limits (i.e. kills the killer after taking the blood-money), he shall have a painful torment.

(2) And there is (a saving of) life for you in Al-Qisas (the Law of equality in punishment), O men of understanding, that you may become Al-Muttaqun (the pious - See V.2: 2).

(3) The sacred month is for the sacred month, and for the prohibited things, there is the Law of equality (Qisas). Then whoever transgresses the prohibition against you, you transgress likewise against him. And fear Allah, and know that Allah is with Al-Muttaqun (the pious - See V.2:2).

(4) And do not kill anyone whose killing Allah has forbidden, except for a just cause. And whoever is killed wrongfully (Mazluman intentionally with hostility and oppression and not by mistake), We have given his heir the authority [to demand Qisas, - Law of equality in punishment - or to forgive, or to take Diyah (blood money)]. But let him not exceed limits in the matter of taking life (i.e he should not kill except the killer). Verily, he is helped (by the Islamic law).
