You may wish to first begin with defining what you mean by "slave", and what is the Quranic term you are referring to.
You may be surprised at how helpful that is. See this excellent past discussion

Thanks Wakas, it was a good thread.
I noticed you pointed out that it wouldn't make sense to free a slave where they had willingly made an agreement to serve (which could be for a number of reasons) so from that I can see it is important to be clear on what I mean by using the term slavery. Rightly or wrongly I wouldn't consider a deal made by one person who owes another to work off that debt slavery unless certain rights were being taken from that person alongside. For example if the person is held captive in anyway, unable to communicate freely, unable to choose for themselves who they socialise with, what the eat, how they keep their money, I guess those things would be examples.
But then today there are many agreements, military would be a good example I guess, where many rights are taken from people when they 'sign up' but they are usually aware of those things and thereby agree to the them.
A.W. thanks for you post and I am sadly aware of slavery's continued existence so I'm with you on that wholeheartedly.
You wrote "Bear in mind though that certain jobs, such as servants at a household is also understood to be slavery. That doesnt mean that all of those households are horrible to their slaves. Often these unfortunate people dont have the means to be independent. So, freeing them can also be understood to give them the means to become independent."
I don't feel that someone who is a servant should be considered a slave unless they are being treated as such, in which case I would consider that wrong. I hope I'm understanding you correctly, but isn't to say that they may not have the means to be independent suggesting that they are being treated as slaves, as opposed to workers with lives and rights? The should be working in someone's home as a servant with pay and the right to family, friends, choices and so on.
Man of Faith Thanks for your input. "Yes, slavery has always been wrong. Many people are also confused by the ancient kind of employment that involved several years of servitude but where the servant was let free for a compensation. Ancient world contract."
I admit I don't know much about any ancient world contracts but what you describes sounds fine to me, unless there is 'servitude' that is somehow forced and where basic rights are taken away from the person. I guess that is where my issue begins.
runningwithzebras I apologise for my overly blunt comments to you, you do indeed have a right to express yourself, and I appreciate you trying to help. While I note you believe that the threads discussions are entirely related, for me, perhaps because I don't claim to be proficient in the study of Quran, nor do I really enjoy getting bogged down in it, it has ended up too complex (for me).
Frankly when this happens, as it seems to often do on here, it makes wonder - I mean, how in gods name is Quran supposed to be advice for all time if we have to expend this much effort to understand anything - and even then, as evidenced here, nobody can agree on anything!
