CIRA International uncover Islamic social system; caring for slaves?

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

Islam controlled slavery in such a way that it made the maintaining of a slave a great responsibility for the master, who had to show them so much care that in many cases when the slaves were set free they did not like to leave their masters. That is why within the Islamic community, it was seen as shockingly ungrateful for a slave to suddenly desert his guardians. It is in such context that the prophet reportedly condemned as kafir/denier a slave that unexpectedly deserts his guardian who did not harm him, but instead gave him shelter when he needed it and sustenance.

In his famous sermon in 'Arafat, on 9th Dhul-hijjah 9 AH, during his last pilgrimage, the Prophet said,

"...and your slaves, see that you feed them such food as you eat yourselves and dress him with what you yourself dress. And if they commit a mistake which you are not inclined to forgive then sell them, for they are the servants of Allah and are not to be tormented..."

As a side note, the selling refered to here is certainly not in the context of trade. It is the best solution for both parties to seperate with lesser harm. The guardian is here confronted to a situation where the slave comits a grave offense. The prophet's compassionate words refer to the slave's misdeed as a mistake, although from the guardian's perspective it is unforgivable and deserving of a harsh treatment. This wording of the prophet is in line with the Quranic injuntions of being more lenient towards the weaker members of society in case of an offense 4:25.

The conditions for having a slave in Islam, as already shown, is costly. Parting with them could not be done immidiately because the guardian had to recover some of his investment somehow. He would thus be tempted to become harsh towards his slave until he could get back some of his costs and then free him. The prophet thus proposes a pragmatic solution that keeps in view justice, with the guardian recovering some of his investment, and compassion, with the slave avoiding punishment and being transferred to a new household where he could have a fresh start.

From Risalat al-Huqooq

"And the right of your subject through being your slave is that you should know that he is a creature of your Lord and is made of the same flesh and blood. And you only own him, but you are much too inferior to God and you have not created him. And you have not created his hearing and sight, nor do you provide his daily sustenance; rather it is God who gives you sufficiency for that. Then He subjugated him to you, entrusted him to you, and provisionally consigned him with you. So protect him there, and treat him well, just as He (God) has treated you well, and feed him with what you eat yourself, and clothe him with what you clothe yourself. And do not burden him with what he cannot withstand. And if you dislike him, you ought to let him go and replace him, but do not torment God's creature. And there is no power but in God".

Slaves are even covered by the law of equal retribution

"Samurah ibn Jundub narrated that the Prophet had said: “He who kills his slave shall be killed, he who amputates his slave shall be amputated and he who castrates his slave shall be castrated.”

Another repercussion of the Islamic system of "slavery", is that when captured during a battle against Muslims, those prejudiced individuals whose aim really was to annihilate Islam by all means, suddenly find themselves under the guardianship of those they believe represent evil. Instead of being mistreated or even killed as they would have done had they captured Muslims instead, they benefit from strict regulations that guarantee their well-being. These people who, like in our days, were brainswashed with a distorted image of Islam, were shocked at seeing and experiencing the truth behind the scenes, benefiting from it, and how just and fair a social system it was as compared to their own society and how they themselves treated their slaves and war prisonners. They experienced the reality of divine justice and many converted. So by restricting the acquisition of slaves to war prisonners, Islam was (and is still in case war is waged on Muslims because of their religion) actually giving them a chance of reform by introducing them to a better system on all levels

8:70"say to those of the captives who are in your hands: If Allah knows anything good in your hearts, He will give to you better than that which has been taken away from you and will forgive you, and Allah is Forgiving, Merciful". 

The voluntary assimilation and conversion of war prisonners because of having witnessed Islam from within, parallels with what happened during the treaty of Hudaybiyyah. It provided a relative peace era on the Meccan front which allowed Islam to spread faster than it ever did, because it allowed Muslims and non-Muslims to visit eachother and interract on account of their family relationships and trade connections. Many Meccans started visiting Medina, and stayed there for months. They got acquainted with the teachings of Islam and were deeply impressed by the righteous conduct and moral integrity of the Muslims, and how they treated the prisonners of war, integrating them into the fabric of society. Islam gained many converts in its ranks during that period.

This sense of brotherhood which Islam gave the oppressed, helped gradually bring down social barriers. As a result, in the early periods of ISlam after the prophet, we see countless slaves with high political responsibilities, including the command of armies, governorship and judgeship. Not only in administration, we find theologians, commentators of the Quran, traditionists, jurists and authors who either were slaves or the children of the slaves or ex-slaves.
