The word(s) "justly" appears 25 time(s) in 23 verse(s) in Quran in Abdullah Yusuf Ali translation.

(11) Will ye not fight people who violated their oaths, plotted to expel the Messenger, and took the aggressive by being the first (to assault) you? Do ye fear them? Nay, it is Allah Whom ye should more justly fear, if ye believe!

(12) Verily Allah will not deal unjustly with man in aught: It is man that wrongs his own soul.

(13) One Day every soul will come up struggling for itself, and every soul will be recompensed (fully) for all its actions, and none will be unjustly dealt with.

(14) One day We shall call together all human beings with their (respective) Imams: those who are given their record in their right hand will read it (with pleasure), and they will not be dealt with unjustly in the least.

(15) (Saying): "Eat of the good things We have provided for your sustenance, but commit no excess therein, lest My Wrath should justly descend on you: and those on whom descends My Wrath do perish indeed!

(16) We shall set up scales of justice for the Day of Judgment, so that not a soul will be dealt with unjustly in the least, and if there be (no more than) the weight of a mustard seed, We will bring it (to account): and enough are We to take account.

(17) Is it that there is a disease in their hearts? or do they doubt, or are they in fear, that Allah and His Messenger will deal unjustly with them? Nay, it is they themselves who do wrong.

(18) "And withhold not things justly due to men, nor do evil in the land, working mischief.

(19) Except those who believe, work righteousness, engage much in the remembrance of Allah, and defend themselves only after they are unjustly attacked. And soon will the unjust assailants know what vicissitudes their affairs will take!

(20) Not one (of them) but rejected the messengers, but My punishment came justly and inevitably (on them).
