CIRA International seek specific examples; the prisonners of Badr?

In answer to the video "The Unknown History of Islam 07 - Islamic Slavery Introduction, Part 1"

The divine grant of mastery over their enemies doesnt give Muslims sanction to treat them as they wish. As shown earlier whether in the Quran or through the practice of the prophet, Muslims must treat them with care, almost as full members of a household. The reason being that through an exemplary conduct those former enemies might open their eyes to the real, unfiltered truth of Islam, free from the distortions of those that only seek to disparage it, and possibly reform themselves. The prophet once commented 

"you bring them tied in chains on their necks (capture them in war) and they later embrace Islam". 

This comment was utterd in relation to the verse qualifying Muslims as the best of nations, conditionally on their rightful conduct and forbidding evil. It is precisely this uprightness that turned enemy combatants, captured in war, into Muslims.

However, because the Quran repeatedly speaks of freeing slave as an act of great virtue, it warns against creating situations that could lead to the captivity then ransoming of slaves, through the example of the Jews of Medina. They entered into alliances with warring pagan tribes and fought, killed, enslaved then freed their own brethren while considering it a "pious act" 2:83-85. Such a behavior would not only be against the letter of the law but also its spirit 

"Malik related to me that he had heard that Abdullah ibn Umar was asked whether a slave could be bought on the specific condition that it was to be used to fulfil the obligation of freeing a slave, and he said, "No"...Malik added, "There is no harm, however, in someone buying a person expressly to set him free". 

Malik continues that in his opinion, the best course of action in this case is to exclude non-Muslim slaves. Choice must be made among those who neither were in the process of being freed, nor burdens to the owner due to physical impairement or bearing his child. A Muslim slave belonging to any of those categories is therefore not a valid kaffara/atonement. Even if he wasnt of those categories, Malik describes the slave as mu'min, meaning sincere and pious believer, which has more merit than simply being labelled Muslim. This way the intrinsic worth of the slave is enhanced to the maximum 

"Malik said...There is no harm in freeing a christian, jew, or magian voluntarily, because Allah, the Blessed, the Exalted, said in His Book, 'either as a favour then or by ransom,' (Sura 47 ayat 4) The favour is setting free".

The very fact of calling the manumission of slaves one of the greatest acts of charity, piety and benevolence towards men 2:177,9:60,90:11-18 shows that having them in one's possession is not the preferred way ultimately even though a short term captivity in the specific context of wars is sometimes necessary. 

The captives of the very first Islamic battle of Badr, were freed on ransom (in form of money depending on each prisoner's financial capacities or work like teaching ten Muslim children how to read and write), while those of the tribe of Tay were freed without any ransom. Some would reform themselves and cease their hostilities towards the Muslims, but others would go back headlong into battle whenever the chance to fight and kill Muslims presented itself. 

For example Abu Izza was among the anti-Muslim coaltion at Uhud. He had been taken as a prisoner of war at Badr and then released by the prophet without a ransom because he was poor and had a large family. The condition for his release was that he would not take part in further anti-Islamic activities, especially verbal provocations, as he was known for his eloquence. If relatives were captured they could not be separated. It is then that the Quran progressively introduced the notion of freeing slave benevolently as a great virtue. 

As already noted, slaves were a source of livelihood and labor, even to Muslims who had to treat them with care. That is why it is considered a great act of generosity if done unconditionally. Even if the person wasnt prepared to go to such charitable extent, the Quran still encouraged freeing them through other avenues such as atoning for certain sins like missing a fast, breeching a vow made hastily concerning a lawful thing, accidental homicide, and many other small acts common in this society 4:92,5:89,58:3. As an act of virtue, Ali emancipated 1000 slaves, purchasing them from his own money. The Prophet emphatically stated on many occasions that, in the sight of God, the unconditional freeing of a human being from bondage is among the most praiseworthy acts which a Muslim could perform.  

No religion other than Islam promoted the liberation of fellow humans in bondage as an act of humanity and virtue, beautifully reflected in Sura 90. That is a fact the Judeo-Christian critics of Islam, who try misrepresenting Islamic slavery with their twisted biblical paradigm in mind, will have to deal with. The overarching approach of Islam towards slavery, as already seen and as will be further developed, is thus to reduce the access to servitude and expand the way towards freedom.
