The word(s) "free" appears 67 time(s) in 58 verse(s) in Quran in Mohsin Khan translation.

(11) It is not for a believer to kill a believer except (that it be) by mistake; and whosoever kills a believer by mistake, (it is ordained that) he must set free a believing slave and a compensation (blood-money, i.e. Diya) be given to the deceased's family unless they remit it. If the deceased belonged to a people at war with you and he was a believer, the freeing of a believing slave (is prescribed); and if he belonged to a people with whom you have a treaty of mutual alliance, compensation (blood-money - Diya) must be paid to his family, and a believing slave must be freed. And whoso finds this (the penance of freeing a slave) beyond his means, he must fast for two consecutive months in order to seek repentance from Allah. And Allah is Ever All-Knowing, All-Wise.

(12) When you have finished As-Salat (the congregational prayer), remember Allah standing, sitting down, and (lying down) on your sides, but when you are free from danger, perform As-Salat (Iqamat-as-Salat). Verily, As-Salat (the prayer) is enjoined on the believers at fixed hours.

(13) And to Allah belongs all that is in the heavens and all that is in the earth. And verily, We have recommended to the people of the Scripture before you, and to you (O Muslims) that you (all) fear Allah, and keep your duty to Him. But if you disbelieve, then unto Allah belongs all that is in the heavens and all that is in the earth, and Allah is Ever Rich (free of all wants), Worthy of all praise.

(14) When he saw the sun rising up, he said: "This is my lord. This is greater." But when it set, he said: "O my people! I am indeed free from all that you join as partners (in worship with Allah).

(15) And your Lord is Rich (free of all needs), full of Mercy; if He wills, He can destroy you, and in your place make whom He wills as your successors, as He raised you from the seed of other people.

(16) And when a community among them said: "Why do you preach to a people whom Allah is about to destroy or to punish with a severe torment?" (The preachers) said: "In order to be free from guilt before your Lord (Allah), and perhaps they may fear Allah."

(17) It is not for a Prophet that he should have prisoners of war (and free them with ransom) until he had made a great slaughter (among his enemies) in the land. You desire the good of this world (i.e. the money of ransom for freeing the captives), but Allah desires (for you) the Hereafter. And Allah is All-Mighty, All-Wise.

(18) freedom from (all) obligations (is declared) from Allah and His Messenger (صلى الله عليه وسلم) to those of the Mushrikun (polytheists, pagans, idolaters, disbelievers in the Oneness of Allah), with whom you made a treaty.

(19) So travel freely (O Mushrikun - See V.2:105) for four months (as you will) throughout the land, but know that you cannot escape (from the punishment of) Allah; and Allah will disgrace the disbelievers.

(20) And a declaration from Allah and His Messenger to mankind on the greatest day (the 10th of Dhul-Hijjah - the 12th month of Islamic calendar) that Allah is free from (all) obligations to the Mushrikun (See V.2:105) and so is His Messenger. So if you (Mushrikun ) repent, it is better for you, but if you turn away, then know that you cannot escape (from the Punishment of) Allah. And give tidings (O Muhammad صلى الله عليه وسلم) of a painful torment to those who disbelieve.
