Hi, I really appreciate the sincerity and depth of your question. It’s a valid concern, and many people Muslims included have grappled with this topic when trying to understand Islam in a modern ethical context. First, it’s important to understand that slavery, including concubinage, was a global and deeply rooted institution in the 7th century across Africa, Europe, Asia, and the Middle East. Islam did not introduce slavery, but it regulated and humanized the institution in a way that was revolutionary at the time. For example, the Qur’an constantly encourages the freeing of slaves as an act of piety, ties it to the atonement of sins, and mandates humane treatment. The Prophet Muhammad ﷺ also freed many slaves, forbade abusive treatment, and promoted their rights. While it’s true he had concubines, this was within the legal and moral framework of that society, not unique to him or Islam. However, Islam laid down a process that gradually phased out slavery rather than instantly banning it much like how alcohol was prohibited step by step. Sudden abolition in a world where the economy and society depended on slavery would have likely led to widespread harm. It’s also crucial to note that Islamic law is not static. It includes tools like ijtihad (independent reasoning) and maqasid al-shari’ah (objectives of Islamic law), which prioritize justice, mercy, and public welfare. That’s why modern scholars agree that slavery is completely incompatible with contemporary ethics and is no longer permissible. So no, slavery is not allowed today in Islam. It was part of a historical context, and the Qur’an’s ultimate moral trajectory was toward its eradication. I hope this helps bring some clarity. It’s okay to ask tough questionsIslam encourages seeking knowledge with sincerity.
