The word(s) "equality" appears 3 time(s) in 3 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) O ye who believe! the law of equality is prescribed to you in cases of murder: the free for the free, the slave for the slave, the woman for the woman. But if any remission is made by the brother of the slain, then grant any reasonable demand, and compensate him with handsome gratitude, this is a concession and a Mercy from your Lord. After this whoever exceeds the limits shall be in grave penalty.

(2) In the Law of equality there is (saving of) Life to you, o ye men of understanding; that ye may restrain yourselves.

(3) The prohibited month for the prohibited month,- and so for all things prohibited,- there is the law of equality. If then any one transgresses the prohibition against you, Transgress ye likewise against him. But fear Allah, and know that Allah is with those who restrain themselves.
