Muhammad Qutb
Sayyid Qutb, the scholar of the Islamist Muslim Brotherhood wrote in his exegesis ("Tafsir") of the Quran that slavery was adopted by Islam at a time it was practiced world-wide for a period of time "until the world devised a new code of practise during war other than enslavement." Qutb's brother, Muhammad Qutb, contrasted sexual relations between Muslim slave-owners and their female slaves with what he saw as the widespread practice of pre-marital sex in Europe.
