The word(s) "freeing" appears 6 time(s) in 5 verse(s) in Quran in Mohsin Khan translation.

(1) 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.

(2) 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.

(3) And those who make unlawful to them their wives by Zihar and wish to free themselves from what they uttered, (the penalty) in that case is the freeing of a slave before they touch each other. That is an admonition to you (so that you may not repeat such an ill thing). And Allah is All-Aware of what you do.

(4) And he who finds not (the money for freeing a slave) must fast two successive months before they both touch each other. And he who is unable to do so, should feed sixty Miskins (poor). That is in order that you may have perfect Faith in Allah and His Messenger. These are the limits set by Allah. And for disbelievers, there is a painful torment.

(5) (It is) freeing a neck (slave)
