Slavery is a phenomenon that torments the soul of wise people from the enslavement and exploitation of human beings. Slavery has existed since ancient times, but only its forms have changed. Although the abolition of slavery has been attempted in recent centuries by humanitarians and those who believe in human dignity, different countries have legally attempted to abolish it, unfortunately, slavery has not yet ended and continues in its new form.According to the latest International Labor Organization (ILO) report, more than 40 million people worldwide are victims of "modern slavery." Although modern slavery does not yet have a legal definition, the ILO says it includes "forced labor, forced marriage, trafficking and human abuse." Contrary to popular belief, many think the West has been modernized, and Western countries continue to use medieval thought to turn to sexual slavery against women and make money using it. According to some estimates, there are about 13,000 cases of slavery in British courts. Modern slavery is like slavery in the past, and it is the largest lucrative trade in the country. Sexual exploitation, forced labor, home service, and sexual exploitation have become the biggest problem in the UK. .The abolition of slavery was enacted in the Great Britain Act of 1833 and in the United States in 1865 the Abolition Act. Notable in these two major events, which mark a turning point in the history of abolition, is that both of these events did not take place with purely humanitarian intentions and were linked to economic and political interests. In the case of Britain's tax exemption, and in the case of the United States, Abraham Lincoln's military tactic of winning over the South, whose economic base was landownership and slavery, was to overcome the enemy and prevent the disintegration of the United States. Although the consequences were effective in abolishing slavery and eliminating the oppression of slaves.Islam has fought the phenomenon of slavery since its inception. The strategy which Islam took towards freeing slaves was gradual, such as the liberation of the slave was great to worship, the obligatory atonement for some sins, and the granting of the right to book a contract with the master for his/her own freedom, etc. Slave-taking prisoners of war was a temporary tactic of Islam, which, if freed the captives, remained a future threat to Islamic society, and if they were imprisoned, they would have been a huge economic burden to the new Islamic society. Therefore, Islam took the captives as slaves and divided them into Muslim houses, but advised Muslims to treat them like a member of their families.If Islam had completely forbidden slavery at once, it was not logical, because the liberation of slaves at once was not fundamentally in the interest of the slaves. This led to the freeing of slaves in large numbers in society without shelter and proper work from which they could live, and the result, of course, was homelessness, poverty, starvation, and perhaps death, as it occurred in the United States. Unfortunately, Islam did not remain in its main path after his prophet, which is the path of the infallible Imams. The leadership of the Islamic society was removed from the hands of divine leaders and placed in the hands of the Taghuti (Satanic) leaders, otherwise with the strategy that Islam had taken towards slavery, the abolition of slavery would have happened much sooner than the West would have achieved it.
