The word(s) "justly" appears 25 time(s) in 23 verse(s) in Quran in Mohsin Khan translation.

(21) It is Allah Who has sent down the Book (the Qur'an) in truth, and the Balance (i.e. to act justly). And what can make you know that perhaps the Hour is close at hand?

(22) And if two parties or groups among the believers fall to fighting, then make peace between them both. But if one of them outrages against the other, then fight you (all) against the one that which outrages till it complies with the Command of Allah. Then if it complies, then make reconciliation between them justly, and be equitable. Verily! Allah loves those who are the equitable.

(23) Allah does not forbid you to deal justly and kindly with those who fought not against you on account of religion nor drove you out of your homes. Verily, Allah loves those who deal with equity.
