Islam authorizes the taking of slaves as spoils of war.

The Quran does not specifically allow slavery, but it does recognize the existence of slavery during the time it was revealed. It encourages the humane treatment of slaves, urges for their eventual emancipation through acts of charity, and promotes the idea of freeing slaves as a way to seek forgiveness.
Only slavery to Allah (God in English) is allowed in Islam. All other slavery types are not allowed in Islam; as slavery to other human master, slavery to money, slavery to power, slavery to certain habit or addiction as smoking or drinking alcohols. Before Islam era and in the early years of Islam, slavery was spread as a normal trade. Also, in wars the conquered men and women are captured as slaves. However, in Quran rules were set to limit slavery and to eliminate it gradually. Quran and Sunnah (Prophet Muhammad sayings and practices) encouraged Muslims to liberate their slaves as a way to be closer to Allah or as a penalty when committing some sins to be forgiven by Allah. Refer to question below for information on slavery in Christianity.
