Hello Sanaa,
Good to hear from you.
So you say, it says nowhere in the Quran to sleep with women you are not married to but I have shown you Surah 4:24 that says you can sleep with "those whom your right hand possess", which are sex slaves..in fact this is the context in which the verse was revealed,
"It was narrated from Abu Sa'eed Al-Khudri that the Prophet of Allah sent an army to Awtas. They met the enemy, fought them, and prevailed over them. They acquired female prisoners who had husbands among the idolaters. The Muslims felt reluctant to be intimate with them. Then Allah, the Mighty and Sublime revealed:
"Also (forbidden are) women already married, except those (slaves) whom your right hands possess," meaning, this is permissible for you once they have completed their 'Iddah."
(Sunan An Nisai 3333)
This is the whole context of Surah 4:24, Muslim men saw female captives with husbands and were reluctant to sleep with them and Allah revealed a chapter of the Quran saying it was fine for them to do so.
And on "Daraba", I think I have shown you a HADITH showing how the prophet said nobody should question a man on why he beat his wife. If you think a woman should not be beaten or that having sex with a captive slave is wrong, then you are contradicting your prophet...
And if you already contradict your prophet, why do you continue to follow him?
