Unlike the Atlantic slave trade, where the male-to-female ratio was 2:1, the Arab slave trade instead of usually had a higher female-to-male ratio. Concubinage and reproduction served as incentives for the importation of female slaves, although many were also imported primarily to perform domestic duties. In both continents, everything a slave owns is automatically the property of the master as well, however in Arabia, a slave may be allowed to earn money to purchase his freedom and likewise to pay for bridewealth should he marry, the marriage by first requiring the master's consent. If the master were to use his slave for sexual satisfaction, he will not be able to live with a slave belonging to his wife, nor will he be able to have intercourse with a slave if she is co-owned or already married. In America, a man could have intercourse with a slave but it was not very likely, as this was taboo and was not approved of. For a male slave in Arabia, there were limited options if already castrated (which was a familiar practice). , they were used as eunuchs, mostly in the service of mosques or for the protection of harems. A system of plantation labor, developed early, but with consequences so dire that these were relatively rare and often small. The need for agricultural labour, in Islam with large peasant populations, was nowhere near as critical as in the Americas, so this was not successful and slaves in general were mainly destined for the service sector, the men were cooks, porters and/or soldiers. While slaves were sometimes employed for manual labor during the Arab slave trade, this was usually the exception rather than the norm. In America, slaves were guaranteed hard work meant exclusively for males such as ditch men, plowmen… middle of paper… just. If the master does not have sufficient wealth to facilitate this, he must sell, rent, or manumit the slave as ordered. Masters were encouraged to educate slaves, teach them to write/read, etc. Slave owners had no right to harm a slave under Islamic rule, unless the slave had committed a crime, in which the sentence would be reduced. In America, slaves had no right to demand that their livelihood be of the same quality as the master's, the treatment of slaves in the United States was generally brutal and degrading. Flogging, execution, and sexual abuse were common ways to make a slave "behave." Slaves were not educated in a way that did not encourage them to run away or rebel. Punishment was often meted out in response to disobedience or perceived infractions, but slaves were also sometimes mistreated to assert the dominance of their master or overseer..
