Note the tense. It’s present. As in he does this NOW.
I'm not sure about Arabic. The biggest cluster of Arabic speakers on Earth is in Egypt so they kind of dictate ideomatic expressions ~ so I'll guess that the Imam, if he was explaining the Koran, actually did so in "historic present".
Professor Jwadeh at Indiana University regularly did that when discussing the 7th Century ~ so it's possible the Imam wasn't justifying selling female sex slaves in modern times ~ there, in fact, being no such markets in Egypt at the moment.
It’s not only present tense, but the Muslim women too:
