Why is there no Limit to the Amount of Slave Women?

Islam encouraged cohabitation with slaves as another avenue to liberation for them and their children. This may be particularly significant if it is realized that the slave’s offspring were often the children of wealthy owners who kept slaves for domestic purposes (i.e. for household help.) It is further suggested that, to enhance the cause of liberation, Islam did not limit the number of slaves with whom a master may cohabit because the greater the number – the closer to freedom they become. [see Um al Walad].

By placing no limit – it is increasingly beneficial to the slave women because instead of having to become Prostitutes for earning money or fulfilling their sexual needs, all slave women -effected by war- will have a household in which the male responsible over her will; provide for her, and fulfills all her needs for her (including; food, shelter, clothing, and also fulfill her emotional and intimate needs etc.)
