As you requested here are the rights of slaves under Islam. (Again I can provide references as you request them)
a) Muslim men were allowed to have sex anytime with females slaves - Sura 4:3, 4:29, 33:49.
b) Slaves are as helpless before their masters as idols are before God - Sura 16:77
c) According to Islamic Tradition, people at the time of their capture were either to be killed, or enslaved. Shows you that they were at the bottom of the barrel to start with.
d) According to Islamic jurisprudence, slaves were merchandise. The sales of slaves was in accordance with the sale of animals.
e) Muhammad ordered that some slaves who were freed by their master be RE-ENSLAVED!
f) It is permissible under Islamic law to whip slaves.
g) According to Islam, a Muslim could not be put to death for murdering a slave. Ref. 2:178 and the Jalalayn confirm this.
h) According to Islam, the testimony of slaves is not admissible in court. Ibn Timiyya and Bukhari state this.
i) According to Islamic jurisprudence, slaves cannot choose their own marriage mate. - Ibn Hazm, vol. 6, part 9.
j) According to Islamic jurisprudence, slaves can be forced to marry who their masters want. - Malik ibn Anas, vol. 2, page 155.
According to historic sources from Muhammad's time it is even said that Muhammad was a slave trader, although he bought more slaves than he sold.
کسی غلام کو آزاد کرنا کسی مذہب میں ایک بہت ہی بڑی نیکی بتائی گئی ہے۔ کیا آپ جانتے ہیں؟ اسکے علاوہ آپ اسلام میں غلامی اور غلاموں کے ساتھ سلوک کے بارے میں کیا جانتے ہیں؟ اس مسئلے پر بحث تب ہی ہو سکتی ہے جب انسان کو معلوم ہو کہ دوسری طرف کا موقف کیا ہے؟
اسلام میں ایک آزاد شخص کو غلام بنا لینا ایک بہت ہی قبیح گناہ ہے۔ لیکن اگر یہ سب کچھ مسل ممالک میں ہوتا رہا ہے تو اسکو آپ مذہب کی تعلیم نہیں کہہ سکتے، یہ تو حکمرانوں کی حرکتیں ہیں جو کہ ہوس اقتدار، مال اور دولت جیسی چیزوں پر ہمیشہ مذہب کو بیچتی رہی ہیں۔
