Prophet Muhammed did not own slaves!

Only a later century book will make up stories after stories of Muhammed having slaves, let alone trading them. No Muhammed never owned slave, he espoused liberation morality of persons.

INB4 muh ma malakat aymanukum.

They are not slaves, let alone enslaved, they are those maintained by oath/trust (literally Aymanikum) believers (mostly refugees), NOT abda, ebadi, nor ariqqabi. later books other than Quran don't count. One has to do a lot of mental linguistic stretching to make this people slaves.
