The word(s) "equal" appears 50 time(s) in 45 verse(s) in Quran in Abdullah Yusuf Ali translation.

(41) And what cause have ye why ye should not spend in the cause of Allah?- For to Allah belongs the heritage of the heavens and the earth. Not equal among you are those who spent (freely) and fought, before the Victory, (with those who did so later). Those are higher in rank than those who spent (freely) and fought afterwards. But to all has Allah promised a goodly (reward). And Allah is well acquainted with all that ye do.

(42) Not equal are the Companions of the Fire and the Companions of the Garden: it is the Companions of the Garden, that will achieve Felicity.

(43) It is equal to them whether thou pray for their forgiveness or not. Allah will not forgive them. Truly Allah guides not rebellious transgressors.

(44) And voluptuous women of equal age;

(45) Then they rejected him (as a false prophet), and they hamstrung her. So their Lord, on account of their crime, obliterated their traces and made them equal (in destruction, high and low)!
