Sup Path,
One thing that should be noted is that the first call to prayer at the Quba mosque built by Prophet Muhammad (saws) was given in 622 by Bilal - a black slave freed by the Prophet.In Islam only non-muslim prisoners of war(muslims cant/arent suppose to enslave other muslims)or their offspring can become slaves.Additionally, slaves had the ability to enfranchise themselves at their own initiative, without waiting passively for the goodwill of their masters: the procedure known as mukataba allowed them to buy their own freedom with sums which they saved from their work, and which the state frequently augmented with advances -- a measure which the slaveowner had no right to oppose. There are many other hadiths which define Islam's true attitude in this regard. The Prophet said: 'Your slaves are your brethren; therefore whoever has a brother who depends upon him must feed and clothe him in the way he feeds and clothes himself; and should not impose upon him tasks which exceed his capacity; should you ask them to do such things, then you are obliged to help them.' The Sharia takes this injunction, among many others, into account when defining the responsibilities and duties of slaveholders.Also Islamic legislation subjected slaveowners to a set of precise obligations, first among which was the slave's right to life, for, according to a hadith, 'Whoever kills his slave shall be killed by us'. In consequence, the murder of a slave was punished like that of a free man. Slavery in Islam in the past had been tolerated but never encouraged and had been (or was suppose to be anyway
) like a butler or maid would be treated nowadays. Hope that answers you....peace to you
