The word(s) "equity" appears 3 time(s) in 2 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) O ye who believe! Ye are forbidden to inherit women against their will. Nor should ye treat them with harshness, that ye may Take away part of the dower ye have given them,-except where they have been guilty of open lewdness; on the contrary live with them on a footing of kindness and equity. If ye take a dislike to them it may be that ye dislike a thing, and Allah brings about through it a great deal of good.

(2) (They are fond of) listening to falsehood, of devouring anything forbidden. If they do come to thee, either judge between them, or decline to interfere. If thou decline, they cannot hurt thee in the least. If thou judge, judge in equity between them. For Allah loveth those who judge in equity.
